arctan%28-3%2F5%29=-0.54042 (rounded), so tan%28-0.54042%29=-3%2F5,
but -pi%3C-0.54042%3C0
Since tangent has a period of pi,
tan%28pi-0.54042%29=-3%2F5 and tan%282pi-0.54042%29=-3%2F5
so highlight%28x=pi-0.54042%29 and highlight%28x=2pi-0.54042%29 are solutions of tan%28x%29=-3%2F5 and comply with 0%3C=x%3C2pi
