With absolute value, try to think of it as, “the absolute value of…..” the thing that is inside the absolute value bars. “The” implies it’s one thing. So taking the absolute value of -6 or 6 gives …
We started by reviewing the chain rule. Sometimes he would get mixed up and apply something that looked like the chain rule to the end of an integral. For indefinite integrals, you add a constant to …
