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? Well it is, you might recognize it if I put a negative there and a negative there. The antiderivative of negative sine of x, well that's cosine of x. So this whole thing is gonna be negative cosine of x or another way to write this, I could multiply both sides times the negative one and so these would both become positive and so I could write one over y is equal to cosine of x and actually let me write it this way, plus c. Don't wanna forget my plus c's.
