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

If theta=7.5^(@) Find the value of quad sin8 theta*cos theta-sin6 theta cos3 thetacos2 theta*cos theta-sin3 theta*sin4 theta

(sin8 theta xx cos theta-sin6 theta xx cos3 theta)/(cos2 theta xx cos theta-cos3 theta xx cos4 theta)=cot5 theta

(sin theta+cos theta)(1-sin theta cos theta)=sin^3 theta+cos^3 theta

sin theta+sin2 theta+sin3 theta=1+cos theta+cos2 theta

Evaluate the following determinants: (b) |(cos theta, -sin theta),(sin theta, cos theta)| = cos theta (cos theta) - sin theta(-sin theta) = cos^(2) theta + sin^(2) theta = 1

(sin theta + cos theta)/(sin theta - cos theta) + (sin theta - cos theta)/(sin theta + cos theta)= ________

(sin theta+sin3 theta+sin5 theta)/(cos theta+cos3 theta+cos5 theta)=tan3 theta

cos theta-cos3 theta+cos5 theta-cos7 theta=4sin theta sin4 theta cos2 theta

(sin3 theta+cos3 theta)/(cos theta-sin theta)=1+2xx sin2 theta
