[Bridgetl-_-l]

Sir if cos is adjacent/ hypotenuse then won't 90° have 2 adjacent sides?

[nikitaudgave]

Sir your video is first on utube which is not teaching how to rote trigonometric value

[Dskynet]

Why the definition of sin=opposite side/hypotenuse??

[trrorbladez]

Do you need to be able to explain any 90 degree things for GCSEs or is it just 30, 45, 60?

[suraprod]

But Y is not the opposite of the given angle .
I don't get it

[ladeeskeee]

how is sine 90 = y/r i dont get it, where did y/r come from?? its opp/hyp ryt

[Azimsultan]

Sin(90°)=1
Cos(90°)=0
Tan(90°)=infinity

[muhammadridho]

Why X = 0? And also how could the ratio of cos 90 be X/radius? Please explain

[gopiganta]

Sir explain by the formula opp/hypo.How sin 90=1

[RangRasa-twm]

Sir I want sphere volume animation sir
Please

[nandinipatil]

Find Trignometric function of
90 degree
-180 degree
Solve this example

[chris.pbacon]

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

[zainabkamara]

This is the only video that made me understand this stuff, thank you!
