I wanted to be a math major at a small college in 1967. After the first week of calculus the head of the math department called me in and suggested I wasn’t prepared. Instead she used this book to teach a small class covering what I had missed in H.S. I have always been grateful for her getting me started on a solid foundation. I got all A’s in calculus after that.
She's a good teacher wish we had more people like her The teachers I have in my stream are just like read book and take notes no explanation or anything :(
Have you ever wondered how providing the answers to the odd-numbered exercises became the standard practice in Math and Science textbooks? I think that would be kind of interesting to hear how that came about, who came up with the idea to do that in the first place, and how they convinced the entire textbook industry to go along with it. Just a thought.
I share with you this concern since my college days up to nowdays) and I had a thought once that maybe it's because the even numbered exercises can be solved by applying the same idea as in the previous odd one. Just a thought and I don't have such books between hands to check it out
I still pretty much prefer book with answer. I realized that I had made A LOT of mistakes in problems that I am familiar with, because that document I used didn't have answers. My point here is the first stage of grasping about new concepts often difficult, always be careful, because it is Math anyway. Having said that, odd-numbered answers isn't the most ideal but still decent, worth a try
ikr im studying physics hrk rn, and it really sucks that they dont give full solution i have studied math and physics with japanese textbooks, and they have very detailed solutions that nearly is as long as the textbbok itself, with all the key points about it. like u can learn just by reading only the solutions
I am in love with old books, it's like they hold something of inestimable value : knowledge, ideas, concepts, thoughts that our predecessors wrote about during times where technology, artificial intelligence and computers were not born yet, and through their brilliant work they made the world advance a little more each now and then, till we arrive in the century we currently live in. PS. English is my second language, some mistakes probably got in my text
I went to the engineering high school. When we were given our books, we wrote our name in ink on the particular page corresponding to the year, top for spring semester, bottom for fall. That ensured no one could turn in the book issued to us. The first name in my Euclidean Geometry book was on page 24.
Can you explain that a little more? If you wrote your name on page 24, wouldn't that mean you studied in 2024???? Also, why would someone hand in your book?
I really like this format where you pick out an exercise from the book and solve it. It gives a nice taste of what it would feel like to work through the book. Maybe in the future, you could also make it a thing to present an interesting theorem in whatever book you review, and go through the proof in some detail? To me, that's also an important aspect of working through a math book, i.e. understanding the theorems and their proofs :)
Another valid technique with the same result is to use matching coefficients. k^2x^2 + (k+2)x +1 = a(x + t)^2. I won't go through the detail, but expanding the right side and matching coefficients you get three equations with three unknowns (k, a, t) and the solution does produce k = 2 or k= -2/3. However, the easier and quicker solution is as you presented and solve for the discriminant equal to zero. Great video as usual!
@@TheMathSorcerer Dear Math Sorcerer, I enjoyed this video, especially because I was able to follow the maths problem you demonstrated. Now, just as Sheldon on The Big Bang Theory would need to solve the final equation by substituting in the ( - 2/3 ) for k , we must also, and would greatly appreciate it, if you would also do so, so, we know we have the correct answer. If you could, please make a part two to this video, showing the working out, and the answer.
Hi. Somehow I’m subscribed to your channel. I don’t know why cuz I really suck at math. Fascinating to see you solving this very strange equation but I absolutely have no idea what’s going on. Don’t know what this type of equation is for or what purpose it serves. Would be nice to know I guess. Other viewers’ comments are gems, seems like everyone’s a mathematician. A very nice community.
I want to thank you, you've rekindled my passion for math. Also I want to correct my last comment in another video: I said that a good strategy in math self-study is to get an early edition of a text. I have been using the second edition of Niven and Zuckerman An Introduction to The Theory of Numbers. I now realize that the discussion of the proof that x^4 + y^4 = z^2 has no solution in positive integers is easier to understand in the third edition. The proof is the same but some more words have been added that makes it a more gentler and friendlier proof. Elementary number theory is so fascinating, and changes my attitude to what I thought were adhoc concepts in some mathematics. If you want to consider the integer solutions of an algebraic equation, you need some what seems to be unnatural concepts and definitions. Also I find some of the problems to be really beautiful. I am now going to rewrite the proof to understand it better. It uses Fermat's technique of infinite descent.
I just added the original 1960 edition of this book to my library. The first two pages of the book walks you through the proof (by contradiction) that the square root of two is an irrational number. Contains a nice chapter on mathematical induction, the binomial theorem, and progressions. Also contains a good chapter on the theory of equations. Chapter 13 on permutations, combinations, and probability is not in the original edition.
A simple method is doing it by sum of the roots and product of the roots Two equation two variable(k and the root say a) problem. I guess it would be more easier than dealing with quadratic in k.
The value of k would be 2. Because when you substitute the value of k in the main equation, you would satisfy the condition of equal roots, i.e, D = (b*b) - 4ac =0. Put k = 2, which gives you the quadratic equation as 4(x*x) + 4x + 1 = 0 => a = 4, b = 4, c = 1; D = (b*b) - 4ac = (4*4) - (4*4*1) = 0. Put k = -2/3, which gives you the quadratic equation as 4(x*x) - 4x +3 =0 => a = 4, b = -4, c = 3; D = (b*b) - 4ac = ((-4)*(-4)) - (4*4*3) = -32 which is not equal to zero. That's why k = 2 is the solution for the given raw equation in the question. Regards A Math Fan
The discriminant is equal to (k + 2)(k+ 2) - 4(k)(k). Substituting k = -2/3 gives (4/3)(4/3) - 4(4/9) = (16/9) - (16/9) = 0. Both answers would have to be correct because they were determined by setting the discriminant to 0 in the first place.
You made a mistake in your substitution into the original equation. You should have gotten 4(x*x) + 12x + 9 = 0, giving the repeated root x = 3/2. I think when you squared (-2/3), you forgot to square the bottom of the fraction, meaning you multiplied by 3 instead of 9 when you tried putting everything over a common denominator. You also accidentally flipped the sign of your b term from 4x to -4x.
In the same subject area, I'd be very interested to get your impression of Seth Braver's books. (They're new, recent, and in print, but exceedingly cheap for that). Specifically, "Precalculus Made Difficult" and "Full Frontal Calculus"). On the vintage side, apart from the legendary Allendoerfer and Oakley's Principles of Mathematics, which seems hard to get a hold of -- impossible for the 3rd edition, which is rumored to be the best -- I hear absolutely tremendous things about some of the old UK O-level/GCSE and A-level materials. One particularly standout name is J. K. Backhouse (Essential Pure Mathematics, then his First and Second courses in Pure Mathematics for A-level). I'd be very interested in your thoughts, and I'm happy to share more names as well.
The first book (Algebra & Trigonometry by Cameron) looks identical - no IS identical in appearance - to my version that I sold to a Maryland used bookstore (or maybe donated to the local library fundraising sale - I forget) long ago. It had been gifted to me (relative in the St Louis area) as an already used book... with someone else's name already written in it, if I recall.

You could also just go straight from (k + 2)^2 - 4k^2 to (3k + 2)(-k + 2) by noticing you have a difference of two squares. (k + 2)^2 - 4k^2 = (k + 2)^2 - (2k)^2 = (k + 2 + 2k)(k + 2 - 2k) = (3k + 2)(-k + 2)

Good morning! I have three observations to your presentation: first: is necesary that k is diferent of zero and too the formula of the roots of the quadratic equation is not true, why? this is a question that must be asked. second: you have to be careful when talking about complex numbers, because when d < 0 the square root of d in the field of reals does not exist and you are entering a new field of numbers that you have to define the root of complex numbers that is not done in high school and is used by custom that is brought from the time of contests where you had to show that you knew how to solve equations better than your opponent. third: the equation d=0 which is equivalent to (x+2)² - 4k² = 0 is easy to solve, because it suffices to observe that the left hand side is a difference of squares and can be factored obtaining: (3k+2)(2-k)=0 solutions are not x=-2/3 ; x=2 ; why? is another question that you must answer. Well, I wish you a good day!
At the point you had the discriminant, you could have taken advantage of the fact that you had the difference of two squares, factored them, and it would have given you k =2 and k = -2/3.

When solving such a problem, you need to ensure that a = k^2 is not zero, so the equation is quadratic. Without this you could have k=0 as one of the solutions. Even though in this example you dont, in other problems you can get wrong answers because of that

Good morning!
I have three observations to your presentation:
first: is necesary that k is diferent of zero and too the formula of the roots of the quadratic equation is not true, why? this is a question that must be asked.
second: you have to be careful when talking about complex numbers, because when d < 0
the square root of d in the field of reals does not exist and you are entering a new field of numbers that you have to define the root of complex numbers that is not done in high school and is used by custom that is brought from the time of contests where you had to show that you knew how to solve equations better than your opponent.
third: the equation d=0
which is equivalent to
(x+2)² - 4k² = 0
is easy to solve, because it suffices to observe that the left hand side is a difference of squares and
can be factored obtaining:
(3k+2)(2-k)=0
solutions are not
x=-2/3 ; x=2 ;
why? is another question that you must answer.
Well, I wish you a good day!
At the point you had the discriminant, you could have taken advantage of the fact that you had the difference of two squares, factored them, and it would have given you k =2 and k = -2/3.

Sir please make a video on the topic of geometry books , love you from INDIA 🇮🇳🇮🇳
I fear that whenever i read and apply what I've learned it always wrong. I want someone to tell me that I'm doing it wrong
does anyone know where do i get this book??
I put a link in the description:)

1. Get person's name
2. Get title of math book
3. ?
4. Profit
Perfume companies will have to come up with a new formula for a perfume that will fit the bill of being the Math Sorceror's favourite perfume. No prizes for guessing that it would be one that would smell like the inside of books.
LOL!

Nice video and nice book, The question isn't hard though
I mean, do you see your family with all these books
