When theta is 90 degree the hypotenuse and opposite side are the same and when we divide a number with the same number we get 1 for example if the hypotenuse is 10 units then the opposite side will also be 10 units (only when theta is 90 degree) and when we divide 10 by 10 we get 1. Thus, the value of sin 90 is 1.
@ladeeskeee3506 the origin / positive half of the x axis is the side you start at. Then the angle swings over to the positive half of the y axis, which makes the y axis the opposite, leaving the distance between the positive x and y axes the hypotenuse. Thus sin=opp/hyp AND sin=y/r! I hope that helps you visualize this! I just figured it out myself - pretty confusing, ngl.
Thanks sir, I understand it.
Sir your video is first on utube which is not teaching how to rote trigonometric value
Sir if cos is adjacent/ hypotenuse then won't 90° have 2 adjacent sides?
In maths, hyp. Is always defined as hyp not an adjacent
Thank you, I understood right away
Please share this video with your friends thank you 👍
Why the definition of sin=opposite side/hypotenuse??
I really understood clearly
Please share this video with your friends and subscribe to my channel
Are you sure you understood clearly? 🤫🤔🤔🤗🤗
Do you need to be able to explain any 90 degree things for GCSEs or is it just 30, 45, 60?
Thank you sir
Hypotheses is r?
Why X = 0? And also how could the ratio of cos 90 be X/radius? Please explain
x is 0 because the point on the graph is clearly lying above the origin (0,0), but since its above the origin it must have a y value.
Thanks bhai ❤️
감사합니다
how is sine 90 = y/r i dont get it, where did y/r come from?? its opp/hyp ryt
Sir explain by the formula opp/hypo.How sin 90=1
Please sir

sağ olun hocam
Tq sm sir
Thanks a lot sir.
Please share this video with your friends and subscribe to my channel thank you 🙂
Sin(90°)=1
Cos(90°)=0
Tan(90°)=infinity
Tq sir.
But Y is not the opposite of the given angle .
I don't get it
what is OJ ? you are sounding OJ.
Why y=r?
Because Y is nothing but the distance from the origin to point P...
Sir I want sphere volume animation sir
Please
Find Trignometric function of
90 degree
-180 degree
Solve this example
Solve
-180 degree
This is the only video that made me understand this stuff, thank you!
Please share this video with your friends thank you 🙂🙂
why sin 90 y/r
Definiton of sin = opposite side/hypotenuse or y/r
@@BRMATHSCLASS but how is it y/r ive never learnt that repond broooooooo

Why do the even teach sin= o/h they should just teach the definition from the video.
