`(1 + sec 2 theta)(1 + sec 2^(2) theta)(1 + sec 2^(3)` is equal is

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 : (tan 2^n theta)/(tan theta) = (1+sec 2theta) (1+ sec 2^2 theta) (1+sec 2^3 theta) … (1+ sec 2^n theta)

prove that : (tan 2^n theta)/(tan theta) = (1+sec 2theta) (1+ sec 2^2 theta) (1+sec 2^3 theta) … (1+ sec 2^n theta)

The expression,(1+sec2 theta)(1+sec4 theta)(1+sec8 theta) is equal to -

sec^(4) theta - sec^(2) theta is equal to

The value of tan((theta)/(2))(1+sec theta)(1+sec2 theta)+(1+sec2^(2)theta)...(1+sec2^(n)theta) is

sec^(4)theta - sec^(2)theta equals

If tan theta = 1/sqrt7 " then" ((cosec^(2) theta -sec^(2) theta))/((cosec^(2)theta + sec^(2) theta)) is equal to
