You should be able to do all the problems in section 9.3 that have been assigned. For problems that require you to find the equation of the tangent line to the graph of the function f(x) at a given point (x1,y1), the hint is first you find the derivative of the function. Then you can find the slope of the tangent line by plugging x1 into f '(x): m = f '(x1). Now you have the slope and the point (x1, y1), you should be able to find the equation of the tangent line.

Your

**FIRST MIDTERM**is on 02/06. There will be aon Tuesday 02/05, 7:30pm-9pm, LCB225.**review session****What you need to know to review for Midterm 1 (on section 9.1 through what we go over in class on Friday 02/01)?**

Make sure you understand and are able to do all

**the example problems**we went over in class.All the

**homework problems**.You can also work on problems in the chapter 9 review section to study for the exam.

**Review Session**on Tuesday 02/05 (**7:30pm-9pm, LCB225**)**Review Problems**(Click here). Answer for Problem 7(a): [9*x^(1/2) – (7/3)*x^(5/6) – (1/3)*x^(-2/3)]/[3 – x^*(1/3)]^2**CALCULATORS ARE NOT ALLOWED**FOR THE EXAM because you don't need them.

**What you need to know to review for Midterm 2 (on section 9.6 through section 10.4)?**

Make sure you understand and are able to do all

**the example problems**we went over in class.All the

**homework problems**. A good way to study is to look at the**solution online**that I post for every HW set.You can also work on problems in the chapter 9 and 10 review section to study for the exam.

**Review Session**on Thursday 03/06 (**7:30pm-9pm, LCB222**)**Review Problems**(Click here)**.**The answer for problem 1(c) should be 20x – 6 + (3/4)x^(-5/2). The answer for problem 2, the critical points should be (4, -19.05), not (4, -24).**Make sure you know the steps of carrying out the 1**^{st}**-derivative test and the 2**^{nd}**-derivative test to find relative maxima and relative minima. Also the steps of how to use 2**^{nd}**derivative to find the concavity and points of inflection of the graph of the function**.**CALCULATORS ARE NOT ALLOWED**FOR THE EXAM because you don't need them.

Overall, many people did not do well on section 10.1. You should go to the solution online to see how the problems should be done. It is IMPORTANT for you to study for the coming exam.
