So copy and paste. So that is going to be equal to this times cosine e to the x. So this is going to be, let's see, we could put the e to the x out front. We could put the negative out front. So we could write it as negative e to the cosine x times sine of x times cosine of e to the x. So that's this first term here. Plus e to the cosine x times all of this stuff.
