I need help with this as I cannot figure out how to calculate the limit value for this function as $n$ approaches infinity.

I know this is an irrational function, but I'm not able to come to an answer. If I graph this function, there are 2 horizontal asymptotes (positive and negative) but both are irrational.

conversion to radians and substitution $u=\frac{180}n$ is last step.
