ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
I must correct it to '\(\sin\) of an angle'.

ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
You find the opposite side of that angle, and then divide that by the hypotenuse in the given triangle.

ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
And that, ma'am, is the way to find \(\sin\) given an angle.

What do you have to find the \(\sin\) of?

Sin of V

What is the length given?

ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
Actually, 72 is not opposite to V. dw:1343316700534:dw

oh my bad.

Also, hypotenuse is the longest side. Note that the thing I told you applies only for right triangles.

This is a useful mnemonic to remember fundamental trigonometric concepts. Classic: SOH CAH TAO Sin = Opposite side length / Hypotenuse side length Cosine = Adjacent side length / Hypotenuse side length Tangent = Opposite side length / Adjacent side length

Erm, it's SOH CAH TOA @dpflan

cerichards Group TitleBest ResponseYou've already chosen the best response.1
so would it be 21 over 75

okk thanks for your help

heh, right @ParthKohli, my mistake ;)

so would cosX be 72/75
 2 years ago

ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
Um, no. \[\cos = {{\text{adjacent} \over \text{hypotenuse}} \Longrightarrow \cos X = ? } \]
 2 years ago

ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
Adjacent side is \(21\). Hypotenuse is the longest side i.e \(75\).

OK AND TAN X WOULD BE 21/72
 2 years ago

ParthKohli Group TitleBest ResponseYou've already chosen the best response.3
tan = opposite/adjacent

@ali110 thanks

Some people have curly brown hair,they paint black some=sine people have=perpendicular(from people)/hypatenus(from have) so sine=perpendicular/hypatanus curly=cosine brown hair=base(from brown)/hypataneus(from hair) so cosine=base/hypatenus they=tan paint black=perpendicular(from paint)/base(from black) so tan=perpendicular/base whole trignometry in just in line!!!!!!!!!! hahahahaahaha @cerichards
