sec^(2)theta-cos^(2)B=sin^(2)beta+tan^(2)theta

(sec^(2)theta-sin^(2)theta)/(tan^(2)theta)=cosec^(2)theta-cos^(2)theta

Prove the following identities: (tan theta-cot theta)/(sin theta cos theta)=sec^(2)theta-cos ec^(2)theta=tan^(2)theta-cot^(2)theta

tan^(2)theta-tan^(2)(90^(@)-theta)=(sin^(2)theta-cos^(2)theta)/(sin^(2)theta cos^(2)theta)

Prove: (sec theta+cos theta)(sec theta-cos theta)=tan^(2)theta+sin^(2)theta

If sin^(-1)x=theta+beta andsin ^(-1)y=theta-beta, then 1+xy is equal to sin^(2)theta+sin^(2)beta(b)sin^(2)theta+cos^(2)beta cos^(2)theta+cos^(2)theta(d)cos^(2)theta+sin^(2)beta

Prove that (sin^(2)theta+cos^(2)theta)/(sec^(2)theta-tan^(2)theta)=1

Prove that: (sin theta-cos ec theta)^(2)+(cos theta-sec theta)^(2)=cot^(2)theta+tan^(2)theta-1

cos^(2)theta+sin^(2)theta cos2 beta=cos^(2)beta+sin^(2)beta cos2 theta

If sec^(4) theta+ sec^(2) theta = 10 +tan^(4)theta + tan^(2) theta , then sin^(2) theta
