1. evaluate cot 11 pie/6 to the nearest hundred angle given in radians.. is there a way to put this in calculator.

Yes. Put it in radians mode, type in pi/6, and hit the "tan" key. Then use a 1/x key to get the cotangent.

Rounded to three figures it is, yes. More exactly, it is 1.337588.... (radians)
