## anonymous 3 years ago Rewrite the expression 2sin theta (cos theta)(cot theta) in terms of sine or cosine. For this problem, I got started but I don't know what to do next.

$$\large 2sin\theta cos\theta cot\theta = 2sin\theta cos\theta \frac{cos\theta}{sin\theta}$$

I'm trying to figure out how to solve it

5. anonymous

cancel the sin(theta)

6. anonymous

2cos^2theta

Thank you dplanc, I forgot what cot theta was

So why does sin cancle out instead of cos?
