Poor guy - why can't you do cotangent functions in
your head? :-)

Help me out Cecil, anyone?

How about:

cot(x) = tan(90-x)

cot(10) = tan(80) = 5.67

Geesh, I had it, but sure didn't look right ... a walk around the block
and letting things go put all back to right ...

CoT(10) = (1/tan(10))

damn ... moments like these are humbling ...

Sometimes my progress forward is "inversely proportional" to the energy
I apply ... ;-)
