## Math 150 Lecture 002 - Ninth Homework Assignment

This assignment is related to

### For discussion at recitation on T Nov 10 and Th Nov 12.

#### *****REMINDER*****

Exam #4 on Tuesday, November 10 will cover the course material through Chapter 5.

#### MAPLE:

• In the Lab Manual, read the sections on int and Illustrating Riemann Sums, pages 93 - 100. Also read the first page and one-half of dsolve, pages 101 - 102.
• Go through the worked Sample Problem for Chapter 6, Sections 1, 2, and 3. This material is found on pages 142 - 144 of the Lab Manual. I suggest that you first try to do the problems using MAPLE on your own. Then compare your solutions with those in the Lab Manual.
• Work through Demonstrations #11. (Part of this demonstration will be covered in class the week of November 2.)

READING: Chapter 6 Sections 1,2 and 3.

CORE PROBLEMS: Write up, for your own record, solutions to the Core Problems for Chapter 6 sections 1, 2, and 3.

Core Problems - errors and comments:

• 6.1 #7. There is an error in the statement of the problem. It should read f(x) = x^2, not f(x^2)=x^2.
• 6.3 #21. For this one you should use MAPLE. First enter the command "with(student);" (see page 98 of your Lab Manual). This puts a collection of special routines at your disposal. For this problem you should use the routine rightsum(f(x),x=a..b,n). For a description of the routine, select the word "rightsum" and then choose "Help on Context." This should open a help window with an explanation of the use of the rightsum routine.

OLD FINAL EXAM PROBLEMS: Final Exams for the past eight semesters are included at the back of your Math 150/151 Lab Manual. For this week's assignment you should work the following problems from the old final exams:

 Fall 1996: # none this time Spring 1997: # none this time Fall 1997: # 4, 16 Spring 1998: # none this time
