In this video, we learn about how to do derivatives, or differential calculus, in different types of coordinate systems, like spherical coordinates! We'll focus on the gradient of a function. Rather than simply giving you the equations (you can look them up!), we will look at *where* the equations come from by building out a generic coordinate system to figure out how we translate the gradient. Questions about this or other math topics? Leave a comment and let's tackle it together!
