Merry Christmas and Happy Holidays to all blog viewers. In the previous week we took the test over optimization, related rates, and the non calculator curve sketching. I did very well on the test and aced it! None of the questions were too hard. The related rates that I struggled on the week before the test was cleared up by Mr. Cresswell and videos on YouTube. Also, the questions on the test were much easier than questions on the quizzes. One of the questions I vividly remember from the test involved related rates and the volume of a cylinder. You also had to relate this go a rectangle where x was the circumference of the cone and y was the height. You wanted to know the rate at which the volume changed at a certain length of the circumference x. You can find this setting the radius equal to x/(2pi). Next you plug that back into the volume equation after you take the derivative of the equation. You then are able to find your rate. It's much simpler when you have a picture to follow along with. Thank you for viewing my blog and have a happy holiday. Go math!
