Thread: solving trigonometry equations algebraically

Hello

I am have a problem solving y =3/tan x and y =2sin x algebraically.

I can do it graphically but have to confirm my answer algebraically.

Can anyone point me in the correct direction on how to do this ?

Thanks.

Thanks.

I assume find the points of intersection for the two equations given?

If so set them equal:





Multiply both sides by



Factor out sin(x)




From this we can use the null factor theorem to solve

To e^(1*pi)

Thanks for your assistance.

I really appreciate it.
