tan^(-1)(tan sqrt(1-theta))=sqrt(1-8)

tan^(-1)(tansqrt(1-theta))=sqrt(1-theta) when

tan^(-1)(tansqrt(1-theta))=sqrt(1-theta) when

prove that , tan(2tan ^(-1) sqrt((1+cos theta )/(1- cos theta )))+tan theta =0

(tan3 theta-1)/(tan3 theta+1)=sqrt(3), then the general value of theta

If u=tan^(-1)(1/(sqrt(cos 2 theta)))-tan^(-1)(sqrt(cos 2 theta)) , then sin u=

tan(2tan^(-1)sqrt((1+cos theta)/(1-cos theta)))+tan theta=0

tan ( 2 tan ^(-1)sqrt((1+cos theta)/(1-cos theta)))+ tan theta =0

then the value of the expression E=(sqrt(1+tan^(2)theta))/(tan theta)-(sqrt(1+cot^(2)theta))/(cot theta) is equal to

If phi=cot^(-1)sqrt(cos2theta)-tan^(-1)sqrt(cos2theta) , then show that, sin phi=tan^(2)theta .
