Cotangent trouble

I'm using some simple trig to evaluate angles but can't seem to grasp what I'm doing wrong. I'm starting with the opposite and adjacent sides of a triangle to find an angle, opposite=1 adjacent=5.

So: tanθ=opposite/adjacent; to solve for the angle, cot(opposite/adjacent)=θ

In this case the cot(1/5)=11.3. True.

There doesn't seem to be the right components for this and the results from using a function don't add up. I can't seem to replicate this outcome in grasshopper... What am I missing?

Hello,

Those two methods do the same thing.

Great! I stumbled into a slightly clunkier solution using components (too many really) or (rad(x/y)) in the formula. These are very helpful, thanks!
