ArcSin ArcCos ArcTan

Question

Are these in the works for the next build? I have a piece of software that I am working on that relies on them but there is no way that I can think of to easily get arcsin. Thanks.

Currently, you either can use the Taylor Series to "emulate" an ArcTan function or use an extension.

For usual need, I recommend you to use Taylor Series (see link given by Grzegorz)

Since a Taylor series is a calculus topic, I seriously suggest adding these basic functions to the compiler.  You might want an arctan2 function also that does a 4 quadrant, great for determining heading to something.

Fully agree. I added those in my extension, for my own usage, but that should be included in SmallBasic...
