Question:
I have to use the arctan function but there are onlyarcsin and arccos in VB. And arctan is not equal toarcsin/arccos. I have lost almost all of my trigonometry background, can you help me?
Answer:
This answer is very simple, you just have the wrong name for the function.
Actually the ArcTangent is a function built into Visual Basic, but it is not called arctan. It is called atan.
