# Implicit differentitation watch

Solve the differential equation dy/dx = sin^2x/y^2 which also satisfies y = 1 when x = 0
2. you need to separate the variables then integrate. you will get one constant of integration which you then find by using the last piece of information.

I have tried to do:
integral (y^2) dy = (y^3)/3
and equate it to integral (sin^2(x)dx) but I don't know how to integrate sin^2(x). I tried to use the integration by parts equation but I kept on repeating the same integration

Try using a double angle formula to convert sin^2(x) into something including cos(2x)
