sec^2theta/(cosec^(2)theta) =

Prove that: sec^(2)theta+csc^(2)theta>=4

sec^2theta+cosec^2theta = ……………….

Show that sec ^(2) theta+cosec^(2) theta geq 4

sqrt (sec^2 theta + cosec^2 theta) =……...

sqrt(sec^(2) theta + cosec^(2) theta)= _________

sec theta + "cosec"theta = 2sqrt(2)

Evaluate , int sec ^(2) theta "cosec"^(2) theta d theta

Prove that (tan theta + cot theta)^(2) = "sec"^(2) theta + "cosec"^(2)theta = "sec"^(2) theta. "cosec"^(2) theta .

sec^(2)theta+csc^(2)theta=sec^(2)theta xx cos e^(2)theta
