Prove that: cot(^2) x- csc x/csc(^2) x
= cos(^2) x- sin x

Solution:

Given that we have to prove:

Take the L.H.S of above

Simplify

We know that,

Therefore,

Also we know that,

Thus we get,

Thus,

L.H.S = R.H.S

Thus proved

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

the correct option is b
