Question 876120
tan (inverse)(tan 200 rad)

I've tied to solve it:
x must be -pi/2 < x < pi/2 

x= 200rad - pi = 20 rad (since tan is periodic)

so tan(inverse)(tan 20rad)= 20rad 
because tan invrse and tan cancel  each other
is my answer correct??
============
tan (inverse)(tan 200 rad) = 200 rad
----
Subtract 2pi repeatedly until it's <= 2pi
= (200 MOD (2pi))*(2pi) =~ 5.221 radians
5.221 is not between -pi/2 and pi/2, so
5.221 - 2pi = -1.0619 radians
