Integration by Partial Fractions
There is no indicator of what the numerators should be, so there is work to be done to find them. If we let the numerators be variables, we can use algebra to solve. That is, we want to find constants A and B that make the equation below true for all x 6= −5,−2. x +14 (x +5)(x +2) = A x +5 + B x +2. We solve for A and B by cross ...

-Substitution - University of South Carolina
people.math.sc.eduJoe Foster u-Substitution Recall the substitution rule from MATH 141 (see page 241 in the textbook). Theorem If u = g(x) is a differentiable function whose range is an interval I and f is continuous on I, then ˆ f(g(x))g′(x)dx = ˆ f(u)du. This method of integration is helpful in reversing the chain rule (Can you see why?)
Integration by Parts - University of South Carolina
people.math.sc.eduExample 4 In Example 3 we have to apply the Integration by Parts Formula multiple times. There is a convenient way to “book-keep” our work. This is done by creating a table. Let’s see how by examining Example 3 again. ˆ x2ex dx. Let g(x) = x2 and f(x) = ex. Then, Differentiate g(x) Integrate f(x) x2 ex 2x ex 2 ex 0 ex + − + Then the ...
