Homework Assignment #5

Due Thursday, March 11, START of Class

There are two parts to this assignment, an online component using the software WebAssign , and a hand-written portion requiring solutions turned in on paper. The WebAssign component is due at 5pm while the written portion is due at the START of class. All problem numbers below refer to Single Variable Calculus, Concepts and Contexts 4th ed., by Stewart, the required text for the course.

The problems assigned using WebAssign are listed here for your convenience. The instructions on WebAssign may be different than those in the textbook. (You can ignore these differences.) It is recommended that you keep any hand-written work used to complete these problems so that you can learn from it later on and have something to refer to should you require assistance. It is expected that when you login to WebAssign to complete your homework, you will be working on your own. Note: Some of the problems on WebAssign are randomized so that they will have different numbers than those in the book. This helps insure students are doing their own work and is a nice way to practice the same type of problem before an exam.

For those problems to be turned in by hand, you should write up your solutions neatly, making sure to SHOW ALL YOUR WORK. Be sure to read the directions to each problem carefully. You are encouraged to work on these problems with other classmates, although the solutions you turn in should be YOUR OWN WORK.

Important: At the top of your written homework, please list the names of any students or faculty who you worked with on the assignment.

Problems to be handed in separately:   7, 10, 16, 18

Hint: For problem #10, use the substitution u = sqrt(x) and rewrite dx in terms of u and du. The new integral in the u variables will be one you can do using the table of integrals.
