If you look at the class website, you can find videos and links that will help with the math/calculus portion of this topic.

^the resources are helpful, but I don't think we will be required to know exactly how to derive using calculus since it wasn't a prereq for this class, just as long you understand the concepts behind it

You can find help in the class resources section. Also, you just need to understand the concepts behind it and how to use the final equations that are produced by calculus.

It is difficult to understand integrals without the knowledge of derivatives, which is just another word for slope. I have attached two links to explain the two.

Will we be expected to integrate or derive any formulas or will they be provided to us?

one way to think of integrals is by looking at a graph. If you have a normal equation, say y=2x, the slope of that equation is 2, so the derivative of that equation is 2 because no matter what x you put in, the slope there will always be 2! For integrals, you're basically given the slope of x at any value, and you are finding the original equation! If you integrate the derivative of 2, you get 2x+ a constant C. It's just the opposite.

They will be provided but it's good to know how to do them to understand the concepts fully

Hello!

All these people gave amazing resources, just wanted to add a graphic that helped me understand it!

The derivative is shown as the slope of the graph, while the integral is shown as the area under the curve of the graph.
