` tan^2theta+1/(sin^2theta)=`

(1+tan^2theta) sin^2theta

If theta=30^@ , verify that: (i) tan2theta=(2tantheta)/(1-tan^2theta) (ii) sin2theta=(2tantheta)/(1+tan^2theta)

Prove that : tan^(2)theta-sin^(2)theta=tan^(2)thetasin^(2)theta

If cot theta = 1 , find the value of : 5 tan^2 theta + 2 sin^2 theta - 3

If sec^4theta+sec^2theta=10+tan^4theta+tan^2theta, then sin^2theta= 2/3 (b) 3/4 (c) 4/5 (d) 5/6

If theta is an acute angle and sintheta=costheta , find the value of 2tan^2theta+sin^2theta-1

The number of roots of (1-tan theta) (1+sin 2 theta)=1+tan theta for theta in [0, 2pi] is

Solve the equation (1-tan theta) (1+ sin 2theta) = 1 + tan theta

What is the value of sin^2theta+1/(1+tan^2theta) ?

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