20 common optimization problems (how to set up)
Get the file: https://www.patreon.com/blackpenredpen/posts/how-to-set-up-20-169957520/Most students don't fail optimization on the calculus, they fail on the setup. Translating word problems into a single, solvable function is the ultimate bottleneck in Calculus 1. I worked through 20 optimization problems to cover every primary setup pattern you will encounter on an exam: 1. Distance minimization 2.Area and perimeter constraints 3.Cost and revenue optimization 4.Trigonometric setup models
