## Midterm III Review for Math 126, Spring 2010

#### Topics we covered.

1. the definition (and idea)
2. they all differ one from the other by only a constant
6. the power rule for ADs
2. definite integrals
1. basic idea: to compute the area under a curve (for a general integrand), or the distance traveled (if the integrand is a velocity function).
2. notation
3. a formula in terms of a limit of Riemann sums -- what the terms in the formula mean and how to calculate (in simple situations)
4. consequences of the formula:
1. computes signed area, not just area
2. sum rule for definite integrals
3. CMR for definite integrals
4. formula for the definite integral of a constant function
5. what happens to the definite integral when the bounds of integration are switched
6. expression of an integral from a to b as a sum of one from a to c and one from c to b
7. comparison properties of definite integrals
3. the Fundamental Theorem of Calculus, in versions as FTC1 and FTC2.
1. to compute values of a definite integral, when you know (or can figure out) an AD of the integrand
2. to compute derivatives of functions built out of definite integrals to varying endpoints
4. indefinite integrals — a table of such
5. the Net Change Theorem
6. the substitution rule
1. looking for a piece which is a function of a function, so the inside part can be called u
2. computing du in terms of dx.
3. changing the whole integrand to be in terms of u only, with no more x's
4. changing the endpoints to their values for u if working on a definite integral
7. integrals of even or odd functions over symmetric domains (so, integrals from -a to a)
