AP Calc: Week 15 - Math

Guess what we did this week?? It's really shocking! We did math!!! Such exciting stuff! We worked on more story type problems, which were kind of difficult. The hardest part is finding the equations and plugging in the variables correctly. For example, I get really confused when two things are coming towards each other, it throws me off how one of them is negative and the other one is positive. I never know which one is which, and that often times makes me have an incorrect answer. We also have learned about more inplicit differentiation problems, which I honestly feel pretty confident about. WZhen we first learned about implicit differentiation, I was very very confused. HOwever the more we have done them the more I understand them.THe only thing that throws me off is when we find the derivative of x, I forget that it is one. Since dx is given, isn't the derivative whatever dx is? I don't know, but it confuses me. Anyways, this has been a really productive week and I am SO excited for Christmas!!!
