## Calculating angles

Apr 19 2009 | 3:25 pm
Hey people
This is my first post on this forum. I am quite new to max/msp, but I'm getting the hang of it.
I have been searching the documentation, and also been searching this forum, but I cannot seem to find what I have been looking for. Therefore I have decided to ask you guys.
I am wondering if there exists an object in max/msp that makes it possible to take the reversed cosine (also sin and tan). When looking in the documentation it says nothing about it.
But I need my program to calculate the angles in a triangle so if you guys could help in any ways, it would be most appreciated.
Just to explain:
I am able to do the following: sin(A) = x / dist cos(A) = y / dist tan(A) = y / x
But I want to do this:
A = reversed-sin(x / dist) A = reversed-cos(y / dist) A = reversed-tan(y / x)
I hope that you understand, and that you can help me. Best regards Johnny

look for [asin] etc. vb

I have spottet that one, but it seems to be giving the result in radians (or something). I need degrees.

generally all those trigonometric functions calculate in radians. but it really doesn't matter much, as the conversion to degrees is simple.

I did not know the expr object. It seems to do the trick.
Thanks a lot.
