Find `(sec^(4)theta-1)/(Sec^(2)theta+1)=`

Evaluate the following (sec^(2) theta -1 ) (cosec ^(2) theta -1)

Find the maximum value of 1-sec^(4)theta-2sec^(2)theta

Find the maximum value of 1-sec^(4)theta-2sec^(2)theta

Prove that (sec4 theta-1)/(sec2 theta-1)=(tan4 theta)/(tan theta)

Prove that , (1+sec 2 theta) (1+sec2^(2) theta)(1+ sec2^(3)theta)... ( 1+sec 2^(2) theta) = (tan 2^(n) theta)/tan theta

Prove that : (sec 8theta - 1)/(sec 4theta - 1) = (tan 8theta)/(tan 2theta)

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

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