Stewart – Calculus – 5.1 / 5.2 – Areas and Distances / The Definite Integral

Approximating Area Using Rectangles

The Definite Integral

Calculating a Definite Integral Using Riemann Sums — Part 1

Calculating a Definite Integral Using Riemann Sums — Part 2

Three equations that give formulas for sums of powers of positive integers:

These formulas are simple rules for working with sigma notation:

Stewart – Calculus – 4.5 – Summary of Curve Sketching

Mnemonic Device for Remembering Steps in Curve Sketching

A. Domain
B. Intercepts
C. Symmetry
D. Asymptotes
E. Decrease or Increase
F. Local Maximum and Minimum
G. Concavity and Points of Inflection

Dill Chips

“This is a dill chip.”

Now, think of this phrase as, “Dis a dill chip.”
This phrase is close to, “DISADILCIP.”

Use the first letters to reconstruct the steps: Domain, Intercepts, Symmetry, Asymptotes, Decrease/Increase (intervals), Local max/min, Concavity, Inflection Point.
