I’m a 39 year old who does nothing related to any of this. I did well in languages and literature/philosophy, etc, but struggled in science and math. I have absolutely no reason to be here but suddenly I’ve been utterly fascinated by math and science. I’ve been studying the Bible and ran across Chuck Missler who was brilliant in both science and theology and now I want to know all about the mathematics and sciences God created. And you know what? Suddenly it all makes sense. This teacher is one of the absolute best!
Hi, 41 here. I’m back at college post bachelor’s (‘07) to study physics for a radiology program. I agree with you and this teacher is amazing. The Bible is a good read. So many people pretend to be religious but have never actually read the book.
I learned this in College and was surprised to see that I still remember all of it. Thanks for the lessons they're very good for review. I also Use: these reminders. SOH, CAH, TOA. that way I never forget.
THIS is how you teach! Anyway, I just want you to know that you're appreciated, and I'm glad that I found your channel. I've always struggled learning anything math related, but through your videos, I've truly "learned" how this works.
Inrerstingly enough, the relationships between SOH, CAH and TOA are the same as the relationships between E, I and R in Ohms law. Same with C, pi and D. Because of that, I like to put them inside a bubble or pyramid just like we do for Ohms Law for a visual reminder.
Another excellent video. However I have a question. Your explanation of vertical and horizontal makes sense for computing force vectors that we're familiar with e.g. throwing a ball. But when thinking of triangles in general, a given triangle can be displayed in many positions; most of them have sides that are not vertical or horizontal. And the sense of vertical and horizontal does not apply in all cases. Also, when focusing on one of the small angles, its opposite side is not the opposite side of the other small angle. Shouldn't this general viewpoint be considered also? I apologize if you cover this in another video. You are gifted to explain so many subjects. Many thanks!
EASY WAY to remember these relations is to just memorise the word SOHCAHTOA. Sine is opp.over hypotenuse (SOH) - Cosine is adj. over hypot.(CAH) - and Tangent is opp. over adj.(TOA).
This is amazing i'm i love your channel so much 😭💘💘it gave me a better understanding in years,,!! Question= do i have to use the calculator to define the angle?
The calculator will give you the sine/cosine, other wise you have to look it up in a special book called an index. This is why modern calculators are so great. Imagine doing physics with an index!
thank you for this!!! non trad student going back to college and need physics. This is a general question, for the most part, in an alg based physics class, is this the majority of trig that will be used in physics? like If I can grasp this, most if not all of the trig someone will use in alg based physics will be comprised of this? I am only asking as I dont want to take trig just to take phys... if i know I can get this, I can be somewhat comfortable knowing theres not this massive amount of trig I am not away of! thank you and i do mean in the general sense... if this is 85+% of the trig I need, I would feel good to go.

You have so much to talk about everything else, but nothing on how to figure out angle degrees without using a calculator! How people did it before calculators? haha, If I want to know the degree of the (theta angle or what is the angle degree is you're not show how to figure it out with out a calculator. Remember calculators only been around not more than 100 years and angle have exist for 1000 years. Show me some math on how to figure the degree of an angle manual math only.
I hear your frustration but you cannot really do it without a calculator. Before calculators textbooks were filled with tables in the back of the book where you would calculate the sine and cosine or the inverse sine in the inverse cosine. Also slide rules existed which if I’m not mistaken could allow you to calculator but that’s just a type of calculator as well. This is why we focus on the special angle such as 30° 60° 45° 90° and so on because those are easy to remember but other intermediate angles you’re just not going to be able to do without a calculator unless you have a super human memory.
I can't figure out how he got 0.69995 for the law of sines section in the following example, see example below. Which values or properties did he use? I've tried many different types of calculations and I can't arrive at 0.69995. I understand everything else in the example. I love your channel.thanks! drive.google.com/file/d/1Z0vbVEJ_-_h9nindld6L8_mLZid3CZel/view?usp=drivesdk
tip to remember the essential trig functions is to remember the term "SOH CAH TOA". SOH = sin (opposite over hypotenuse), CAH = cos (adjacent over hypotenuse), TOA = tan (opposite over adjacent)
Came here to learn physics (I'm in high school and was just interested) I am now essentially a master of mathematics so thanks I guess I always thought I was bad at math but I just needed motivation and my motivation was that I wanted to learn physics I'm now doing basic algebra in school and doing college level maths in my free time
11:36 ( I'm just playing ) Sin of 90=1 Cos of 0=1 I only know that from watching your videos and thinking. I loved the video where you talked about shining a flashlight, that is the one that started opening my eyes. The unit circle video was awesome. After watching Equation of a Circle I started plotting my own incrementally. That helped me understand some of the other lessons.
You always give us the angle degree but don't show how you came up with the degree without a calculator. You're missing a very important part of the equation, not way man
great video, but not what I search for, question: its possible calc out degree just knowing length of legs, and not use calculator or sinus(cosinus) table? its possible or not?
I looked it up one time. I found a formula, but it was so complicated it would take years of math to ever get to that point, I stopped trying to figure out how to do it w/out calculator.
@@zcsaba77 I do not remember where I found it. It did take quite a bit of searching, but I did find it. The information is out there. All I can say is good luck finding it. ps if you ever figure it out & can explain it, I would love to hear from you.

Thank you so much!!! This was very helpful in helping me understand how Trig is used in biomechanics.
I wish this guy had been my math teacher!
Dude, you're amazing. You make trig look so simple and easy to understand. Thank you.
Thank you very much, great explanation! Looking forward to more video's to get me through my course!
Thank you so much!
Great video. Writing basic components of problems on a blank sheet of paper really helped with exams. It reduced my anxiety to focus on what I knew.
I followed you until the end when you said the angle is the inverse sine of opposite over adjacent. What does inverse sine mean ?
Inrerstingly enough, the relationships between SOH, CAH and TOA are the same as the relationships between E, I and R in Ohms law. Same with C, pi and D. Because of that, I like to put them inside a bubble or pyramid just like we do for Ohms Law for a visual reminder.
Hi, I think this time there's an error here : inverse sine of .6 is 40.966...°, same result as inverse cosine of .8. Is this right? Thanks
thank you just made me understand why we add 180 if the angle is negative

The title does say Review of Essential Trigonometry, (as you say, for physics) not for general coverage. Great job!

Knowing this you can solve any right angle trigonometry problem
Sin goes with y and opposite is in the y axis that way I don’t forget
You’re amazing thank you!
How can sin-1 (0.6) be found by caculator? anyone know, tell me the way
Press 2nd on the graphing calculator and than hit SIN. Then from there enter 0.6 in the ( ) and hit enter.
Your calculator must be in deg mode.
Great review of my colleague days. 😃
What if the angle is given
THANK YOU... SO MUCH

I always use “SOH CAH TOA” to remember.
Yes, I must also call on the venerable old “Indian Chief” to help me remember. 😊
You are the best! Subscribing on your website. 😍
Thanks so much!
Awesome! 👏
good lesson

Lowkey thought he was a DR. at first. The font and the attire contributed to my assumption 😂
ISOSCELES TRIANGLE = 3 equal sides
NO. Isosceles triangle and TWO equal sides, not three. Three equal sides are an equilateral triangle.
The sound is unfortunately impaired many times during the lesson !
Would you please upload again ?
Interesting though😅

Why do the values squares of the two sides he calculated not equal 100?

I am confused where did you get 36.87 degrees how to calculate?
Thanks for proving 25 = 25. I didn't know that
Pls am confused here ,how to get that inverse function
Thank you sir 🙇🏻♂️
Thanks very much sir
thank you for this
Excellent thank you
You always give us the angle degree but don't show how you came up with the degree without a calculator. You're missing a very important part of the equation, not way man
You can’t do it without a calculator or a table of values other than the special angles such as 30,60,45,90 degrees. That is the reason.
I wish I would've found your channel fall 2020 so I would've avoided retaking precal twice
How the hell did he get 0.6 he skipped a step
How? 3/5 in decimal form is 0.6. Thats basic 4th grade math.
starting vector math in 3d calculus and was struggling with basic trig. this is helpful thankyou bossman
OMG. It took weeks before I realized opposite was theta. Where were you 6 years ago ?
Give us some examples on how to calculate the degree of and angle come on
The order of selecting the topics of physics and your teaching both are superb
