evaluate cot 11 pie/6 to the nearest hundred angle given in radians.. is there a way to put this in calculator.
another ?
use a calculator and inverse function to find radian measures of the given angle
angles whose tangent is 4.21 is that 1.34 the answer?

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)
