Dear Firends,

I have a small doubt. It may seem a little preposterous. But stil i need your help.

I wanna develop a logic to find inv Cos(X)'s value and Sqrt(X).

For Eg CosX=2 and i want to find the value of X. ie X=Inv cos2

X²=A and i want to find X=Sqrt (X)

Please tell me a solution friends.
