Prove that sec^4theta-sec^2theta=tan^4theta+tan^2theta .

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)=

If tan theta + sec theta = n, then sec ^(4) theta - tan ^(4) theta- 2 sec theta tan theta =

Prove that: 2sec^(2)theta-sec^(4)theta-2csc^(2)theta+csc^(4)theta=(1-tan^(8)theta)/(tan^(2)theta)

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

Prove that 2sec^(2)theta-sec^(4)theta-2csc^(2)theta+csc^(4)theta=(1-tan^(8)theta)/(tan^(4)theta)
