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

generally all those trigonometric functions calculate in radians.

but it really doesn’t matter much, as the conversion to degrees is simple.
