I've been up for hours trying to figure out the proper notation to prove problem #4 (1.6.5) on the attached files. I'm not sure how to set this up. It is basically proving the product rule using the gradient of two functions. The rest of the problem is on the backside file, but help getting started on the first part would be enough. Any help would be greatly appreciated. Thanks!(adsbygoogle = window.adsbygoogle || []).push({});
