Y to the negative two, y to the negative two. These become one and then we can also multiply both sides times dx. So if we multiply dx here, those cancel out and then we multiply dx here. And so we're left with y to the negative two power times dy is equal to sine of x dx and now we just can integrate both sides. Now what is the antiderivative of y to the negative two? Well once again, we use the reverse power rule. We increment the exponent, so it's gonna be y to the negative one and then we divide by that newly incremented exponent.
