Prove :sec^(6)theta=tan^(6)theta+3tan^(2)theta sec^(2)theta+1

Prove that following identities sec^(6)theta-tan^(6)theta-3tan^(2)thetasec^(2)theta=1

Prove that following identities sec^(6)theta=tan^(4)theta+3tan^(2)thetasec^(2)theta+1

Prove: sec^6theta=tan^6theta+3tan^2thetasec^2theta+1

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)

x=a sec^(3)theta tan theta,y=b tan^(3)theta sec theta then sin^(2)theta=

x=a sec^(3)theta tan theta,y=b tan^(3)theta sec theta then sin^(2)theta

If sec^(4) theta+ sec^(2) theta = 10 +tan^(4)theta + tan^(2) theta , then sin^(2) theta

Prove the following identity : sec^6 theta- tan^6 theta=1+3 tan^2 theta+3 tan^4 theta .
