Tuesday 9/29
In our homework from over the weekend we learned the chain rule which is: 1.) (dy/d//x//) = (dy/du)(du/d//x//) 2.) if f(//x//) = g(h(//x//)), then f'(//x//) = g'(h//(x))// **x** h'(//x//) 3.) to differentiate a compostie function, differentiate from the outside function with respect to the inside function. Then multiply the derivative of the inside function with respect to //x//.

Problem of the day:

We discovered that the derivative of ln(x) = 1/x for x values greater than 0

You should know these:

Practice problems: Some of you have been asking about the solutions to a worksheet which involved sketching graphs of f '(x)and f "(x) from the graphs of y = f(x).Here is the answer sheet.

Thursday 10/1
Test 3 today. See Tests page for a copy of the test and the solutions.

Friday 10/2
Today we learned about the Product Rule for derivative functions, finding the rule using x, y, u, & v, and then doing some examples.
