" 2."sin4 theta-sin2 theta=cos3 theta

(cos4 theta+cos3 theta+cos2 theta)/(sin4 theta+sin3 theta+sin2 theta)=cot3 theta

Prove that : (cos4 theta+cos3 theta+cos2 theta)/(sin4 theta+sin3 theta+sin2 theta)=cot3 theta

Solve sqrt(3)cos theta-3sin theta=4sin2 theta cos3 theta

(sin3 theta-sin theta * sin ^ (2) (2 theta)) / (sin theta + sin2 theta * cos theta) = cos x rarr x =

If cos3 theta+sin3 theta+(2sin2 theta-3)(sin theta-cos theta)>0 then subset of values of theta is

Prove that sin theta+sin2 theta+sin4 theta+sin5 theta=4cos((theta)/(2))cos((3 theta)/(2))sin3 theta

Simplify: (sin8 theta cos theta-sin6 theta cos3 theta)/(cos2 theta cos theta-sin3 theta sin4 theta)

Solve the equation 3-2cos theta-4sin theta-cos2 theta+sin2 theta=0

Show that :((cos theta-cos3 theta)(sin8 theta+sin2 theta))/((sin5 theta-sin theta)(cos4 theta-cos6 theta))=1

A value of theta satisfying 4cos^(2)theta sin theta-2sin^(2)theta=3sin theta is
