Question

How do I solve number 6?

Answer 1

csc^2(theta)

Explanation:

1 / cot^2(theta) = tan^2(theta)

=============

sec(theta) = cos(theta)

therefore sec(theta)*cos(theta) = 1/cos(theta) * cos(theta) = 1

==========

tan^2(theta) + 1 = y

One of the fundamental theorems of trigonometry is

tan^2(theta) + 1 = csc^2(theta)
