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. So we divide by negative one. Well that would just make this thing negative. That is going to be equal to, so what's the antiderivative of sine of x?
