-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 ...

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.

To extract the graph, click on “Export” where you can save the file as an image (PNG, JPG, etc.) or as PDF, these options are useful when you only want to share the graph or use it in a LaTeX document. Probably, the easiest way to export a graph is by copying it to the clipboard and then paste it directly into your Word document.
