Hi,

I know it's possible with VB to get the Sine, Cos or Tan of an angle.

But how can I (if possible) get the invertion?

Like say if I have two textboxes and a command button. I put .8660 in text1. How can I make the angle whose Sine is that appear in text2? (I know in this case the angle is 60 degrees 'cause I checked on the Windows Calculator.)

Thanks!
