Why is that tricky? Do you have a calculator? Do you want a FUNCTION or are you willing to deal with the infinitely many periodic values?
I want some formula to calculate ATAN of given value. Suppose if i have a value of 12.5 i need to calculate ATAN of this value. ATAN(12.5) = ?
Please help me by provinding some information on this.
Thanks & Regards,
