## Homework Statement

I need to find the equilibrium solutions

dy/dt = sin^2 y

## The Attempt at a Solution

I don't know what to do with the sin^2. If it was just sin, it would be easy, 0, pi, -pi, 2pi, -2pi.....etc...... But it's not, I have a Ti-84 plus calculator. So, i don't believe I can put it in my calculator to find out? what do I do???
