## Homework Statement

Simplify cot(θ)sin(-θ) so that it is a single trig function of positive θ

## Homework Equations

## The Attempt at a Solution

I changed cot(θ) to

cos(θ)/sin(θ) X Sin(-θ)/1

I stated that sin(-θ) and sin(θ) were the same and then cancled out the sin(θ) and sin (-θ) to get cos(θ)/1 or Cos(θ)

I feel like this is right but I only got half the points I was supposed to get, not quite sure what I did wrong.
