This week in Calc, we did more integrals, and we were introduced to the idea of slope fields. Slope fields give you a good way to visualize a function from its antiderivative. They can also help you figure out integrals that would otherwise be impossible. We took a quiz on the same topic. I think I did fairly well on it. I finished pretty quickly although I couldn't for the life of me remember that the antiderivative of lnx is 1/x. I probably will not forget that anymore. Other than that I think the quiz went well. We then worked on differentiating for x and y. That led to a conversation about the use of c and k both for arbitrary constants. To illustrate that it doesn't matter what variables one uses, I did algebra with smiley faces to prove my point.
