(1-tan^(2)theta)/(sec^(2)theta)=(1)/(2)

If (1-tan^2theta)/(sec^2theta)=1/2 then the general value of theta is

Statement 1: tan^(2)(sec^(-1)2)+cot^(2)(cosec^(-1)3)=11 . Statement -2 :tan^(2)theta+sec^(2)theta=1=cot^(2)theta+cosec^(2)theta

Statement 1: tan^(2)(sec^(-1)2)+cot^(2)(cosec^(-1)3)=11 . Statement -2 :tan^(2)theta+sec^(2)theta=1=cot^(2)theta+cosec^(2)theta

Prove that |(sec^(2)theta,tan^(2)theta,1),(tan^(2)theta,sec^(2)theta,-1),(38,38,2)|=0.

The determinant |(sec^(2)theta, tan^(2)theta,1),(tan^(2)theta, sec^(2)theta, -1),(12,10,2)| equals

(sec^(2)theta-1)/(tan^(2)theta)=?

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

1+(tan^(2)theta)/((1+sec theta))=sec theta

Prove that (tan^2 theta)/(tan^2 theta-1)+(cosec^2 theta)/ (sec^2 theta-cosec^2 theta)= -sec 2 theta .

Prove that: (1+sec 2theta)(1+sec2^(2)theta)(1+sec2^(3)theta)...... xx )(1+sec2^(n)theta) = tan2^(n)theta* cot theta
