" 30.If "3cos theta-4sin theta=2cos theta+sin theta," find "tan theta

If 3cos theta-4sin theta=2cos theta+sin theta then find tan theta

If 2 - cos^(2) theta = 3 sin theta cos theta , sin theta ne cos theta then tan theta is

Consider f(theta)=|[tan theta,cos theta,sin theta],[cos theta,sin theta,tan theta],[sin theta,tan theta,cos theta]| then f((pi)/(4))+f(0) = ?

(cos theta-sin theta) / (cos theta + sin theta) = sec2 theta-tan2 theta

Prove that :(cos theta-sin theta)/(cos theta+sin theta)=sec2 theta-tan2 theta

(sin theta-2sin^(3)theta)/(2cos^(3)theta-cos theta)=tan theta

Prove that ( cos theta + cos 2 theta + cos 3 theta + cos 4 theta)/(sin theta + sin 2 theta + sin 3 theta + sin 4 theta)= cot ""(5theta)/(2).

2 cos (theta - pi //2) + 3 sin (theta + pi//2) - (3sin theta + 2 cos theta ) = ? A. cos theta - sin theta B. sin theta - cos theta C. sin theta + cos theta D. cot theta - tan theta .

Prove that (cos theta-sin theta)/(cos theta+sin theta)=sec2theta-tan2theta
