-Substitution - University of South Carolina

Joe 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

Example 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 ...

Common examples of sets include the set of real numbers R;the set of rational numbers Q, and the set of integers Z. The sets R+;Q+ and Z+ denote the strictly positive elements of the reals, rationals, and integers ...

with vertical axis, vertex at the bottom, 9 ft deep, and top radius 4.5 ft. Beginning at time t = O, water is poured into this tank at 50 ft3/min. Meanwhile, water leaks out a hole at the bottom at the rate of IOU cubic feet per minute where y is the depth of the water in the tank. (This is con- sistent with Torricelli's law.)

for each x 2I. Then, by formula (7) and the Squeeze Theorem, lim N!1 jR N(x)j= 0 for each x 2I. Thus, by So 7, f(x) = X1 n=0 f(n)(x 0) n! (x x 0)n for each x 2I. 3Here we assume that the (N + 1)-derivative of y = f(x), i.e. y = f(N+1)(x), exists for each x 2I. 4Here we assume that y = f(N)(x), exists for each x 2I and each N 2N. 4

MATH 142 - Integration by Partial Fractions Joe Foster Example 3 Compute ˆ −2x +4 (x2 +1)(x −1) dx. The process follows as before. The most common mistake here is to not choose the right numerator for the term with the x2 + 1 on the denominator. The term of the numerator should have degree 1 less than the denominator - so this term

Interval of Convergence of Power Series

The series converges only at x = a and diverges elsewhere (R = 0) The Interval of Convergence of a Power Series : The interval of convergence for a power series is the largest interval I such that for any value of x in I , the power series converges.
