## Homework Statement

arctan(sin((3 / 4) * pi) * 2) = 0.955316618

I want to express that in terms of a fraction with reference to pi.

## The Attempt at a Solution

I thought of first dividing that by pi itself, and then convert the resulting number into a fraction and tack pi on at the end, but the calculator won't convert the number.
