Use the properties of inverse functions to find the exact value of the expression
Arctan(tan(5pi/3))
Arctan(tan(5pi/3))
sage: arctan(tan(pi/5)).simplify()
1/5*pi

can't make an obvious simplification
Can sage compute the inverse of a function?
Is there a way to set arbitrary function commuting rules?
Sage crashes when inverting a large matrix - alternatives?
Why functions are much slower than var in some calculations?
