Is there a node for reciprocal?

Hi, quick question: how would i set up this Math expression in blueprint:

Cos−1(X/Y)

That should read as the reciprocal of Cos, or 1/Cos.

There doesnt seem to be a reciprocal node, and when i try to use the ‘Power Of’ node i can only do Cos(X/Y)-1 .

Hope the question makes sense, i’m worthless when it comes to math.

You mean Acos(X/Y)?

aahh that’s the one!

I’ve never done math in English before. Thanks!
