Worksheet - Partial fractions Math 142 Page 1 of 9 Evaluate the following integrals 1. Z 2x2 + 19x 13 (x 5)(x 1)2 dx 2x2 + 19x 13 (x 5)(x 1)2 = A x 5 + B x 1 + C (x 1)2 Multiply both sides by the denominator of the right hand side: 2x2 + 19x 13 (x 5)(x 1)2 (x 5)(x 1)2 = A x 5 (x 5)(x 1)2 + B x 1 (x 5)(x 1)2 + C (x 1)2 (x 5)(x 1)2 Canceling ...

Integration by Partial Fractions Summary: Method of Partial Fractions when f(x) g(x) is proper (degf(x) < degg(x)) 1. Let x−r be a linear factor of g(x). Suppose that (x−r)m is the highest power of x−r that divides g(x). Then, to this factor, assign the sum of the m partial fractions: A1 (x −r) + A2 (x −r)2 + A3 (x −r)3 +···+ A m ...

This worksheet completes the lecture on Partial Fractions. When there is an irreducible quadratic (one that cannot be factored into linear factors), the partial fraction expansion has a linear term.

Partial Fractions Worksheet Name February 12, 2007 1. (a) Consider the rational function f(x) = 2x3−4x2−5x+3 x2−2x−3. Use long division to get a quotient and a remainder, then write f(x) = quotient + (remainder/divisor). (b) Now consider the expression x+3 x2−2x−3. Factor the denominator into two linear terms. (c) We wish to write x+3

Feel free to work with a group on any problem. These problems are intended to enhance your knowledge and give you something to bring a boring party back to life.

Algebra and Partial Fractions Math 125 Name Quiz Section Integration of rational functions is mostly a matter of algebraic manipulation. In this worksheet we shall work through some examples of the necessary techniques. 1a Consider the rational function f(x) = 2x3 4x2 5x+3 x2 2x 3. Use long division to get a quotient

WORKSHEET 9 (1) In the following problems, you should write the partial fraction decomposition for the rational func-tion, but do not solve for the constants. For example, for x (x 2 1)(x +1), you should write A x 1 + B x+ 1 + Cx+ D x2 + 1 because the denominator factors as (x 1)(x+ 1)(x2 + 1). (a) x 2 x2 + 4x (b) x2 x 1 (Be careful!

Practice expanding rational functions using partial fractions, and use this method to evaluate integrals. Some \Rules" The purpose of partial fractions is to expand a rational function into a sum of terms.
