The least value of ` 4 sec^(2) theta + 9 " cosec"^(2) theta ` is

Minimum value of 9 sec^(2) theta + 4 cosec^(2) theta + 7 is

The least values of ( sin ^(2) theta+ cosec ^(2) theta) is

If sec theta + cos theta = 2 , then the value of sec^(2) theta + cosec^(2) theta is :

The value of 2 sec^(2) theta - sec^(4) theta - 2 cosec^(2)theta + cosec^(4) theta is

the value of sec^2 theta + cosec^2 theta is equal to

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

The value of cosec ^(2) theta cot ^(2) theta - sec ^(2) theta tan ^(2) theta -(cot ^(2) theta- tan ^(2) theta) (sec ^(2) theta cosec ^(2) theta -1) is-
