How did you find PF?

i was searching up about "differentiability" for calculus, because I don't know how to solve it wo a graph, and then I noticed this website and despite it saying physics, I still clicked. it was the "science by humans" that made me sign up ♡

For schoolwork-related problems (even if for self-study), post in the Homework Help forums and fill out the Template that you are provided there when starting a new schoolwork thread. That includes the Problem Statement, the Relevant Equations, and your Attempt at the Solution. Always show your work on the problem so that we can then provide tutorial help.

The Homework Statement is where you list the problem word-for-word as it is given to you. You can also upload a PDF or JPEG image of the problem if that helps, but it's usually required that you type the problem in as well. The Relevant Equations section is to help you think about and list the equations and formulas and concepts that may be helpful in working the problem. You then show your work in the section below (the main body of the thread start).
