Question

PLEASE HEP! A simplified version of the expression 2sinθ (cos θ)(cotθ) is ?
sin^2 θ
cos^2 θ
2sinθ (cscθ)
2cos^2 θ

Answer 1

2cos^2 θ

Answer 2

Are you sure?

Answer 3

cot is cos/sin

Answer 4

so it can be written as 2sincos^2 / sin

Answer 5

2 sin theta cos theta*cot theta
co=cos/sin
2 sin theta*cos theta*cos theta /sin theta
we get 2 cos^2 theta

Answer 6

which then simplifies to 2cos^2

Answer 7

O thanks
