Using trigonometric identities, sin^2(y) = 1 - cos^2(y).
If you substitute that in, you get 1- cos^2(y)/(1-cos(y)).
You can factorise 1 - cos^2(y) to be (1-cos(y))(1+cos(y)).
This means that the answer is 1 + cos(y) as the 1 - cos(y) will cancel.

This is the answer
Answer:
Linear
Step-by-step explanation:
The trend is a straight line so linear
The trend is not parabola type so not quadratic
The general equation is
- y=mx+b
- The equation of line is y=3x-5
