sec^(4)A(1-sin^(4)theta)-2tan^(2)theta=1

sec^(4)theta(1-sin^(4)theta)-2tan^(2)theta=1

Prove that following identities sec^(4)theta(1-sin^(4)theta)-2tan^(2)theta=1

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

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

sec^(4) theta (1-sin^4 theta ) - tan^(2) theta =

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

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)

tan^(2)theta-sin^(2)theta=sin^(4)theta sec^(2)theta

If : sin^(2)theta+sin^(4)theta=1, "then": tan^(4)theta-tan^(2)theta=
