I have this basic differential equation du/dt=(u^2)*(sin t)(adsbygoogle = window.adsbygoogle || []).push({});

This is obviously a separable diff eq.

So what i've done is:

g(t) = sin t h(u) = u^2

1/(u^2) du = sin t dt

Integrating both side....

1/y = - cos t + c

therefor y = - 1/(cos t + c)

Which is wrong, there isn't supposed to be a minus sign apparently. I don't know what i've done wrong. Any suggestions? Thanks.
