tan^(2)theta+cot^(2)phi+2=sec^(2)phi*cosec^(2)phi

prove that: tan^(2) phi+cot^(2) phi+2=sec^(2)phi cosec^(2) phi

(tan^(2)phi)/(1+tan^(2)phi)+(cosec ^(2)phi)/(sec^(2)phi+cosec^(2)phi)=1

The equation tan^(2)phi+tan^(6)phi=tan^(3)phi*sec^(2)phi is

The value of tan^2 phi+ cot^2 phi- sec^2 phi cosec^2 phi is equal to:

If : cos^(2)theta-sin^(2)theta=tan^(2)phi, "then" : cos^(2)phi-sin^(2)phi=

tan^2phi-sec^2phi = ………………

Consider tan theta+sin phi=(3)/(2) and tan^(2)theta+cos^(2)phi=(7)/(4) then find maximum value of (12(theta+phi))/(pi) if (theta+phi)in(0,2 pi)

If tan^(2)theta=2tan^(2)phi+1, then cos2 theta+sin^(2)phi is equal to

If tan^(2)theta=1+2tan^(2)phi then show that cos2 theta+sin^(2)phi=0
