Caculating trigonometric functions

I have a problem in computing known Sin values into angles. For example, if I got a value of 0.5, i know that is Sin(1/6Pi), and 1/6Pi is euqal to 30 degrees. But what if i got the value of 0.1? I need a trigonometric functions table.
Are there any scripts able to caculate the angles of any Sin values?
Thanks for answering.

Unless you have a huge number of sin, you don’t really need a table or any trigo-tricks. Don’t calculate them unless you have to though.
