A. Mike's Christmas Saving's
B. I am conducting an experiment to find how much money someone can save over the year for Christmas shopping, and the rate of change during those months.
QUESTION: What is the maximum rate of change?
G. On the third month, the rate of change is $40 per month meaning they are saving $40. Mathematically, at three months the slope of the point is 40.
H. The tangent is the derivative, the derivative is the rate of change, and the rate of change is the slope which I solved for by finding two points on the tangent line.
I love how your data had many points. It shows the variety of options you have in order to determine different slopes. Nice job graphing.
ReplyDeleteGreat example with plenty of data points!
ReplyDeleteI like how you have used many scan points to display what you are doing. Furthermore, your work is easy to follow.
ReplyDeletemichael,
ReplyDeletei like your topic, and i like that it was something relevant to you! your graph and table look good, although, it was a little bit hard to see your tangent line. the only thing i would add is to remember to include your units when calculating the secant lines as well as the tangent line. nice job. =]
