" (i) "tan^(2)*theta+(1)/(sin^(2)theta)

The value of (1+tan^(2)theta)(1-sin^(2)theta) is

If (sin theta + cos theta)/(sin theta - cos theta) = (5)/(4) , the value of (tan^(2) theta + 1)/(tan^(2) theta - 1) is

if theta = 45^0 then tan^2 theta + 1/(sin^2 theta)

Prove the following identities: (1+tan^(2)theta)+(1+1/(tan^(2)theta))=1/(sin^(2)theta-sin^(4)theta)

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

(1+tan^(2)theta)sin^(2)theta = ……… .

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

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

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