-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 ...

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.)

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.
