What is the first step. Explain please.
Which expression is equivalent to cos^2x + cot^2x + sin2^x?
a) 2csc^2x
b) tan^2x
c) cot^2x
d) csc^2x
cos^2x + cot^2x + sin2^x

1 + cot^2 x
1 + cos^2 x/sin^2 x
sin^2 x/sin^2 x + cos^2 x/sin^2 x
1/sin^2 x
csc^2 x d)

How did you get 1 + cot^2 x?

cos^2 x + sin^2 x = 1
That should be part of your soul !
