# Math 421:01 - Advanced Calculus for Engineering

**Instructor:** Natalia Komarova, office hours M 1:30-2:30 and W 11:30-12:30, Hill 426; email: komarova@math

**Place:** SEC 204

**Time:** MW 5 (2:50-4:10)

** Main text: ** * Advanced Engineering Mathematics * by Peter V. O'Neil.

** Prerequisits: ** Primarily for mechanical engineering majors. CALC 4. Credit not given for both this course and 01:640:423

** Course description: ** Laplace transforms, numerical solution of
ordinary differential equations, Fourier series, and separation of
variables method applied to the linear partial differential equations
of mathematical physics (heat, wave, and Laplace's equation).

## The grade:

The grade will be decided on the basis of the
two midterm exams (20% each), the final exam (40%), the homework (10%)
and the quizzes (10%). The homework assignments are graded by a
teaching assistant, who is asked to choose three problems at random
for grading. The quizzes are graded by the professor. The worst
homework and the worst quiz are not taken into account.

## Midterm 1 materials:

Date: Monday, March 1.

No calculators or books can be used on the midterm. A formula sheet will be provided.

Sample problems for Midterm 1

Some solutions for sample problems, and more solutions here.

Solutions for Midterm 1 problems.
**ATTENTION** those who got 59 or less for the first midterm. On
Monday, March 22, at 1:30-2:30, Hill 425, you can take a make-up test
to gain up to 25 points to be added to your midterm result. In order
to prepair for this test, please use the
practice sheet. Also, study the Solutions for Midterm 1 problems,
above.

## Midterm 2 materials:

Date: Monday, April 5.

No calculators or books can be used on the midterm. A list of useful matrix reduction facts will be provided.

Sample problems for Midterm 2

Some solutions for sample problems.

## Final exam materials:

Date: Thursday, May 6, 8:00-11:00 am

Place: SEC 204.

No calculators or books can be used on the final. A list of formulas will be provided.

Sample problems for the Final exam, part 3

Some solutions for sample problems.

Sample problems for the Final, parts 1 and 2 are the same as the sample problems for Midterms 1 and 2.
