[25->,17cos10-sin^(2)theta],[,sin theta(1+cos theta)]=cot theta

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

Prove: (1+cos theta-sin^(2)theta)/(sin theta(1+cos theta))=cot theta

Prove that: (sin2 theta)/(1-cos2 theta)=cot theta

Show that ((1 + cos theta - sin ^(2) theta)/( sin theta (1 + cos theta ))) = cot theta

(sin3 theta-sin theta)/(cos theta-cos3 theta)=cot2 theta

Prove that sin(2theta)/(1-cos2theta)=cot theta

Prove : (2 sin theta cos theta-cos theta)/(1-sin theta+sin^(2) theta-cos^(2) theta)=cot theta

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

(sin theta)/(1-cos theta)=cos ec theta+cot 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
