Question: How to get maple to simplify a trig expression

Hi everyone,

 

I'm to simplify the expression cos(x)/sin(x) to cot(x). None of the "simplify" commands seem to work, I've tried assigning the expression to a name "a", then using the "simplify(a,trig)" command and it doesn't work either.

Anyone have any ideas on how I can tell maple to simplify this?
