ACOS & ASIN functions

There’s an ATAN function but not ACOS & ASIN. Is there a way to calculate those from ATAN? If not, could we get ACOS & ASIN in a future release?

I took the math functions from the original BASIC, I guess there is a way to calculate these values. But I had to google it. If it’s complicated then I could add new functions, yes.

It would be good to define ACOS and ASIN, especially as lowres basic does not support user defined functions (like DEF used to in Sinclair BASIC)

ATAN,ACOS,ASIN are just different ways to find the angle...

ATAN is sufficient if you just substitute with what you know into ATAN

Timo, for reasons im not sure how to explain, please don’t impliment this, and if you do impliment this, for the love of god do NOT make it throw an error every time you give it something out of bounds. I’ll make a Subprogram for this.

I'll have a look on these functions. Even some BASICs had ASIN. And I'll think again about DEF FN to define own one-line functions, it's part of the original BASIC...

Coming in the next update (core v0.15):
ASIN, ACOS, HSIN, HCOS, HTAN
