Recent Tutoring Session Reviews
"We went over limits in continuous and noncontinuous functions. The first couple of problems could be solved simply by plugging the x value into the function. The next set required manipulation of the function before the x value could be plugged in, and the last set of problems involved graphing functions and looking at their limits from the positive and negative directions."
"We went over linear approximations of differential equations and how to solve related rates problems of spheres and triangles. We used some online examples, as well as some examples I made up on the spot."
"We went over precise definition of limits and finding the slope of tangent lines to a curve by the limit definition. The student was struggling the most with the understanding of the precise definition of a limit, but once he saw how easy the procedure is to relate delta with epsilon he moved on really fast. I showed him a shortcut to solve a binomial by inspection."
"We went over relative maxima and minima. I gave the student the overview, really only two rules to follow, so it should be relatively easy for her. She doesn't have a problem with derivatives, so the upcoming concepts should be easy for her to grasp."
"We went over several calculus problems (limits, derivatives) and explained the concepts behind them. He seemed to get it better after I explained it, and we did a bunch of problems. "
"We went over some concluding review for the chapter on limits, and then gave him a preview of what he will be studying soon by demonstrating the use of a limit to find the derivative and emphasizing how derivatives are rates of change."
