math for me clicked when the goalpost changed. In school, we need to find the roots of f(x) which is just an excuse for making us do tedious calculations. In college, this is just a step (very important one, but just a step) to achieving a much greater goal, and achieving this goal recquires technique, experience, algorithms and a lot of thinking, of course.This is what math is about, this is why we learn to calculate, to do it easily when the real challenge becomes thinking and breaking thru
Great explanation! Actually the symbols one was cool. Expecting more such videos with detailed explanations on specific concepts like complex numbers and integration. Glad I found this video! Keep it up!
bro this is one of the best videos in maths i have ever seen , even though i didn't understand calculas since i am 10th grade , you explained the root 2 concept so good that i understood it well here than in my class , thanks a lot dude
I don't agree with i=√-1 tbh, Leads to some contradictions. i^2=-1 is a better definition, since the square root is also defined as a positive real number not a complex one
To anyone watching this video that hasn’t been through at least part of high school: Don’t bother commenting that you didn’t understand anything or that it wasn’t "basic." You’ve hardly even grazed the surface of math until you’ve gotten to high school. That’s when you really start learning math. This was a very good video and did explain a lot of concepts that schools fail to.
Watching this after my "CBSE 10th board mathematics (standard ) examinations " . Well, this video will help me choosing subject stream in 11th🗿. Thanks bro🤗. From India
Wait. I thought he will explain level 1 then proceed slowly to level 100. But no, i feel that he starts at level 10. I'm looking for a video that actually explains how we get the alphabet's value such as i, e, pi, etc
videos like these just cover the most basic things in many different regions in math while also giving very little explanation to what they are doing, basically saying "figure it out". But most times people who watch these videos understand what they are watching no one who wants to learn would watch a video like this
this is in no way meant to be a lesson where I teach you something. either someone already knows the content and is revising, or someone watching is thinking about doing further maths, where they 'dip their toe' into more difficult concepts.

It's rather natural, isn't it? You can also invoke the tautology (¬p → q ∧ ¬q) → p: a proof by contradiction of a statement p is a proof that for some q the following implication is true: ¬p → q ∧ ¬q. Using the tautology, we get that p itself is true.
Yes, for example now I will prove that math is useless. Sol. :- Let math (M) be useful Therefore M = $ ……(A) Squaring both sides we get - M² = $² That implies, M = ±√$ ……(B) Comparing Equation (A) and (B) Since money can't be negetive so, $ = √$ But it contradicts the fact that money can't be equal to the square root of it's amount which states that our assumption was wrong. Hence Math is useless
Rather random topics. Talking about the derivative and integral without mentioning limits or the fundamental theorem of calculus (part one and two) is also kinda wild.
Q.E.D. or QED is an initialism of the Latin phrase quod erat demonstrandum, meaning "that which was to be demonstrated". Literally it states "what was to be shown".
For eg when we multiple 2 sides of square to find the area we get side x side as the formula. Anything multiply by itself one time is squared or to the power of 2
Agreed. Also, it's rather improper to use "u" as a random variable, especially when you're involving integration, because you should reserve u for u-substitution.
no. Obviously context matters. u can be used to represent units, or in this case units squared. In this problem, u-sub was not used so there is no confusion around what u means. Even if the problem did use u-sub, it would still be correct to use u^2, though for clarity it would be best to have u for u-sub in italics and u for units in default text. That was not necessary for this case, though.

That's the point. But it's kinda dumb to talk about differentiation and integration without limits or the fundamental theorem of calculus.

you have some mistake here, the i part called imaginary part, and complex mean both real and imaginary as it 2 dimensional so it's complex.

prove that 'proof by contradiction' is actually a valid way of proving things
It's rather natural, isn't it?
You can also invoke the tautology (¬p → q ∧ ¬q) → p: a proof by contradiction of a statement p is a proof that for some q the following implication is true: ¬p → q ∧ ¬q. Using the tautology, we get that p itself is true.
if you assume one thing and it ends up contradicting that which you already know to be true you know your assumption must be wrong
Did someone say *CONSTRUCTIVISM* ?
Yes, for example now I will prove that math is useless.
Sol. :- Let math (M) be useful
Therefore
M = $ ……(A)
Squaring both sides we get -
M² = $²
That implies,
M = ±√$ ……(B)
Comparing Equation (A) and (B)
Since money can't be negetive so,
$ = √$
But it contradicts the fact that money can't be equal to the square root of it's amount which states that our assumption was wrong.
Hence Math is useless

at 4:56, where the hell did u^2 come from? does it just mean units squared or something? if so, why squared?
Because we are finding the area under the curve. The 'u' here means units and raised to power 2 is used when area of any shape is found
For eg when we multiple 2 sides of square to find the area we get side x side as the formula. Anything multiply by itself one time is squared or to the power of 2
