Calc AB Notes and Videos

Notes 01

Limit definition of the derivative; tangent & secant lines; derivative rules; numerical derivatives and finding zeros on calculators; derivatives of the six trig functions; derivatives of e^x and ln(x); some new calculus-style questions.

Notes 02

The Chain Rule is pretty much the last differentiation rule (you’ve still got techniques to learn, but those will just use the rules you’ve already learned). Practice problems with using the chain rule on functions, with tables, with graphs.

Notes 03

Motion along a line (rectilinear motion); position, velocity, acceleration; distance vs. displacement; speed; finding position functions from velocity functions. After these notes we do old FRQs from 1989 (AB3, BC6) and 1990 (AB1, AB2, BC1)

Notes 04

Three part definition of continuity; differentiability; one-sided limits and differentiability; points at which a function is continuous but not differentiable.

Notes 05

Mean Value Theorem (MVT); applying MVT to functions on a given interval; solving MVT problems with your calculator; MVT problems and tabular data.

Notes 06

Implicit Differentiation; common mistakes; second derivative of implicitly defined function; horizontal and vertical tangent lines; derivatives of inverse trig functions; derivatives of exponential functions; review of some geometry-type stuff. After these notes we do a number of old FRQs from 1973, 1978, 1980, 1992, and 1994, all of which featured implicit differentiation.

Notes 07

Print all three! These notes are about related rates. We cover all the classics: falling ladders, cones, etc. Additionally the mastermathmentor.com notes (16) are really good and there are a lot of old FRQs that have great problems. The ones we do: 1970AB4, 1972AB5, 1976AB4, 1977AB6, 1982 AB4, 1984 AB5, 1985 AB5, 1987 AB5, 1988 BC3, 1990 AB4, 1991 AB6, 1994 AB5, 1995 AB5. Notes 07a is the problems, which you have to be in my class to see, but are freely available on the internet, as well, if you google around. Notes 07b is space for doing the FRQs. Also…the shadow problem! Make sure you know and understand that problem!

Notes 08

Understanding where L’Hopital’s Rule comes from; how to evaluate limits that give 0/0 or infinity/infinity; repeated use of L’Hopital’s Rule; an example where L’Hopital’s Rule gets caught in a loop; some review problems.

Notes 09

Finding the value of the derivative of the inverse to a function without being able to find the actual inverse function. Sadly a lot of people lose points for this on the AP Exam when it’s just not that difficult. Also a few review questions.

Notes 10

Function analysis using derivatives (increasing/decreasing/concavity/First and Second Derivative Tests) and the Candidates Test.

Notes 11

These notes do not exist…but when they do, they’ll be about optimization.

Notes 12

Rate times time equals total; definite integrals; displacement; position from velocity graph; tons of definite integrals that can be done geometrically; u-substitution and definite integrals; definite integrals of functions interpreted as area; definite integral properties; some forward looking review problems.

Notes 13

Antiderivatives; Power Rule for Integrals; u-substitution; strange u-substitutions; “simple” initial value problems. Here’s a link to a file that has a lot of u-substitution problems grouped so you can good at doing them in your head.

Notes 14

Approximating definite integrals with sums; Left, right, and midpoint sums; trapezoidal sums; Riemann sums and tabular data; Riemann sums given a function; tons of practice.

Notes 15

Writing summations; using the summation formulas; generalizing a right-Riemann sum; limits of Riemann sums; the Fundamental Theorem of Calculus (FTC); understanding summations and their limits.

Notes 16

Applying the FTC; understanding the FTC; u-substitution and changing the bounds; definite integrals of horrible integrands (calculator!).

Notes 17

The Second FTC; 2nd FTC and critical points; 2nd FTC and limits; typical 2nd FTC and graph problems.

Notes 18

Average value; sketching the rectangle with equal area; average value vs. average rate of change. Here’s a link to a GeoGebra sketch to help visualize average value.

Notes 19

Motion and antiderivatives; the position function as an accumulation function; working with tabular data.

Notes 20

Area of regions bounded by curves; Riemann sums to approximate area; top minus bottom; right minus left; using a calculator; slicing up regions into sub-regions; find a vertical line that divides a region; find a horizontal line that divides a region; a little more on average value.

Notes 21

Approximating volumes with Riemann sums; the most common cross sections; volumes by plane slices; volume from tabular data; volumes of solids of revolution (disks and washers). This video explains a little about volumes of solids with known cross sections (hard to picture, easy to calculate!). This GeoGebra sketch (not by me) is extremely helpful in visualizing volumes with known cross sections.

Notes 22

Density problems. If you’re a teacher pressed for time you could probably skip this and not put your students at a serious disadvantage. I like to cover the concept, especially radial density. Here’s a way to look at radial density functions. (Not super self-explanatory, but you’ll work it out…)

Notes 23

Slope fields; what to aim for; reading slope fields (what to look for); types of solutions and general trends; how to do them on your calculator. Here’s a link to an online version on GeoGebra.org of a sketch that creates slopefields to play around with. See the playlist for videos on creating slope fields on the TI-Nspire (CAS/non-CAS…doesn’t matter) and how to deal with slope field matching problems.

Notes 24

Basic differential equations you already know how to solve; what is a solution to a differential equation; verifying solutions through differentiation and substitution; separation of variables; domains of solution curves; exponential growth models; working with general solutions. This video goes over a few examples that lead to natural logs (and talks about solving for C).

AP Calculus Review Videos

Here’s a link to a google doc where I’ve organized most of my review videos. Start studying now! If you’d rather just look through an enormous playlist of all the videos, here’s a link to that!

Everything beyond this point is not on the AP Calculus AB exam, but will be on the AP Calculus BC exam! ***

Notes 25

Volumes by shells. Not a lot going on here, really, because it’s very straight forward. Think about tree rings and cylinders!

Notes 26

Integration by Parts (IBP); when dv = dx; repeated IBP; the table method (rapid repeated IBP); IBP that loops. Here, here, and here are three videos of examples of pretty much each type. For some reason the second video is the most popular…also, the integral of secant cubed is about as hard as an “easy” integral gets and it uses integration by parts. Here’s a video for that too…

Notes 27

Partial fractions; non-repeating linear factors; cover-up method; repeated linear factors; quadratic factors; using expand on your TI-Nspire CAS. Here’s a video about non-repeating linear factors. Here’s a video about repeated linear factors. Here’s a video about quadratic factors.

Notes 28

L’Hopital’s Rule and the additional cases in which it can be applied; inverting one of the factors; taking natural logs; don’t forget to exponentiate the answer! Here’s a video about 0 times infinity. Here’s a video about the other indeterminate forms.

Notes 29

Improper Integrals; the types of improper integrals; proper notation; practice problems.
