If `tan theta =t, ` then ` tan 2 theta + sec 2 theta =`

If tan theta=t then tan2 theta+sec2 theta=

If tantheta=t then tan2theta+sec2theta=

prove that (tan theta) / (sec theta -1) = (tan theta + sec theta + 1) / (tan theta + sec theta - 1)

If a+b tan theta=sec theta and b-a tan theta=3sec theta then find the value of a^(2)+b^(2)

If x sec theta + y tan theta = a, x tan theta + y sec theta = b " then " a^(2)-b^(2) =

If a+b tan theta=sec theta and b-a tan theta=3sec theta then find the value of a^(2)+b^(2)

If : sec theta * tan theta (sectheta + tan theta) + (sec theta - tan theta) = sec^(n) theta + tan^(n) theta, "then" : n = A)1 B)2 C)3 D)4

Prove that :1+tan theta tan2 theta=sec2 theta

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