Write the values of sec 0^(@) ,sec 30^(@) , sec 45^(@) , sec 60^(@) and sec 90^(@) . What happens to sec x when x increases from 0^(@) "to "90^(@) ?

If x ne 0 , then 1+ secx + sec^(2)x + sec^(3)x + sec^(4)x + sec^(5)x is equal to ………….

The value of sec20+sec40+sec160 is

(1)/(sec A)+(sec A)/(sec A)

sec^4 A - sec^2 A =……….

Prove the following identities : (sec A)/ (sec A + 1) + (sec A)/ (sec A - 1) = 2 cosec^(2) A
