Trigonometric Ratios
This basic trigonometry video tutorial provides an introduction into trigonometric ratios as it relates to a course in geometry. It explains how to calculate the sin, cos, and tan ratio of a right triangle given the 3 sides. You can use the pythagorean theorem to find the value of the missing side. In addition, it explains how to evaluate trigonometric functions using right triangle trigonometry and special right triangles such as the 30 60 90 triangle or the 45 45 90 triangle. This video contains plenty of examples and practice problems including find missing angles as well as missing sides.

MR. Organic Chemistry Tutor, thank you for another well-organized video/lecture on Trigonometric Ratios in Analytic/Plane Geometry. This topic is easy to understand from start to finish. All students should realize that Trigonometric functions are built off Ratios and the Unit Circle.
Wish I found this video a LOOONG time ago Thank u so much!
Ur the best I was having problems in maths class but ur explanations was splendid than my teacher
I mostly study by myself.this video have shown me to get a tutor from youtube
Is it the opposite and hypotenuse same for angle B in the first example. And also what is a the adjacent for angle B is it side 15 or 8 in the first example.
Thank you bro for making this video ✊. Very helpful for revision and now I get it
Omg thx so much this helped a lot!!!

For the last problem, you could’ve also used the Pythagorean identity.
thank you for this! i am stressing with this topic for how many hours.
This actually made me learn the lesson, like while this was being lectured they keep mixing up the terms, but there are still some things that makes it confusing for me, rather like I don't still understand some of the terms , but this helped me big time
THANK YOU SO MUCH!!!!
Thank you very much, you're helping my life

Pls why did u represent it with 1 2 and the square root of 3
how am i going to calcu the answer in 13:52?
wait so at the start of the video where u said sin theta equals opp/hyp therefore it’s 15/17, but how do u know that theta is angle A? it could be C, no?
@asmakazim117
21 сағат бұрын
Theta is representing a variable and as far as i could understand... Sin A means "angle at A". So opposite of angle "A" is 15 and hypotenuse is 17 as it's the longest side of the triangle. Basically, for example Sin A means the angle at "A" And Sin B means angle at 'B" Hope it helps

Where'd one come from 😢 10:28
You shd. put degree of angle A and calculate the ratio as15/17 . You make a mistake by saying A is 8
16:08 - 16:54 It would be appropriate and less confusing if the formula was B^2(X^2) = square root of C^2(52^2) - A^2(20^2) instead, as you are finding Height after all, which is equals to the square root of Hypotenuse^2 minus Base^2. I think this is something a teacher would ask you about. Why use a formula for Hyp^2 when it'd be rational to use the height formula? Just saying.
I got the hang of it.
