-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.)

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.

Equivalent Fractions and Comparing Fractions: Are You My ...

The following rule is always correct when we are comparing fractions. Rule #2 - If the denominators of the two fractions that we are comparing are the same, the fraction with the larger number in the numerator always represents the bigger (greater) fraction. Write Rule #2 on the board for the students to refer to during the remainder of the lesson.

Comparing Fractions Sometimes it is necessary to compare the size of fractions to see which is larger or smaller, or if the two are equal. Sometimes several fractions must be placed in order of size. Unless fractions have the same bottom number (denominator) and thus parts of the same size, you can’t know for certain which
