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

If tantheta=t then tan2theta+sec2theta=

Simplify: tan theta[(sec theta, tan theta),(tan theta, -sec theta)] + sec theta[(- tan theta, -sec theta),(-sec theta, tan theta)] .

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 =

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

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)
