7.sec^(3)theta-2tan^(2)theta=2

If sec^(2)theta+tan^(2)theta=sqrt(3) , then the value of (sec^(4)theta-tan^(4)theta) is

sec^(4)theta-tan^(4)theta=sec^(2)theta+tan^(2)theta

Prove that: sec^(4)theta-tan^(4)theta=sec^(2)theta+tan^(2)theta

If sec^(2)theta+tan^(2)theta =(13)/(12) , then calculate the value of (sec^(4) theta-tan^(4) theta)

If sec^(2)theta+tan^(2)theta=(7)/(12) , then sec^(4)theta-tan^(4)theta=?

The number of values of theta in the interval (-(pi)/(2),(pi)/(2)) satisfying the equation (sqrt(3))^(sec^(2)theta)=tan^(4)theta+2tan^(2)theta is

sec^(6)theta-tan^(6)theta-3tan^(2)theta.sec^(2)theta=?

The value of cosec ^(2) theta cot ^(2) theta - sec ^(2) theta tan ^(2) theta -(cot ^(2) theta- tan ^(2) theta) (sec ^(2) theta cosec ^(2) theta -1) is-

"cosec"^(2) theta * cot^(2) theta -sec^(2) theta * tan^(2) theta - (cot^(2) theta - tan^(2) theta ) (sec^(2) theta * "cosec"^(2) theta -1)=
