Question

sin theta - 2 sin cube theta upon 2 cos cube theta - cos theta is equal to tan theta​

Answer 1

Answer:

(sin theta- 2sin cube theta)/(2cos cube theta-cos theta)=tan theta

Step-by-step explanation:

(sin theta-2sin cube theta)/(2cos cube theta-cos theta)

=(sin theta(1-2(sin theta)^2))/(cos theta(cos theta)^2-1)

=(sin theta/cos theta)*(1- 2(1-(cos theta)^2)/(cos theta(cos theta)^2-1)

=tan theta*(1-2+2(cost theta)^2)/(cos theta)^2-1)

=tan theta*(-1+2(cos theta)^2/(cos theta)^2-1))

=tan theta*((cos theta)^2-1)/(cos theta)^2-1))

=tan theta*1

=tan theta

Answer 2

tan theta- cos theta

tan theta
