I am in the middle of a brain fog/block.

I am attempting to get an equation to obtain the cotangent of x (or 10
in the above.) I HAVE DONE THIS BEFORE-got something wrong here ...

(1/tan(10)) = 5.67128

and (400*(1/tan(10)) = 2268.51273

There is no "built in" cotan function on my ti-86, ti-83, etc.

Help me out Cecil, anyone?
