As requested by @APEXCalculus , this removes the sageplot graphs from the curve sketching section, and replaces them with the original TikZ versions.
There was one more Sage graph at the end of the section. I've changed this one to an external asset rather than a generated asset. I don't think it makes sense to keep Sage as a dependency to build the textbook for just this one image.
