`3(sec^(2)theta+tan^(2)theta)=5`

Prove that: 9sec^(2)theta-5tan^(2)theta=5+4sec^(2)theta

Find the value of theta if sec^(2)theta+tan^(2)theta=(5)/(3) and theta lies in first quadrant.

If sec ^(2) theta + tan ^(2) theta = 5/3, what is the value of tan 2 theta ?

Eliminate theta from the relations a sec theta=1-b tan theta,a^(2)sec^(2)theta=5+b^(2)tan^(2)theta

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

Show that (1)/(3) lt (sec^(2) theta - tan theta)/( sec^(2) theta+ tan theta) lt3 .

If sec^(4)theta+sec^(2)theta=10+tan^(4)theta+tan^(2)theta, then sin^(2)theta=(2)/(3)(b)(3)/(4)(c)(4)/(5)(d)(5)/(6)

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

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

Show that (sec^(2)theta - tan theta)/(sec^(2)+ tan theta) lies between 1/3 and 3 for all real theta .
