1. Riemann Sum
1.1. The Sum. The command sum is used to evaluate denite or indenite sum of expressions.
Let f be an expression with summation index i. Then sum(f,i=m.n) gives the denite
sum of f(i) for i f

Margarine and butter are emulsions formed between fats and water. Fats are known as triglycerides.
They are formed by the reaction of three fatty acid molecules including glycerol which contains three

LESSON 1: BASIC COMMANDS AND CURVE PLOTTING
Maple is a powerful software for doing mathematics.
In this course, we would like to
introduce students this powerful software. We are going to learn how to use certain basic
commands of Maple by
LESSON 5: ORDINARY DIFFERENTIAL EQUATIONS AND
1. Ordinary Differential Equations
Recall that an ordinary dierential equation is a equation that contains functions of
one independent variable and its derivatives with respect to that variable. It

CHAPTER 1: LIMITS
A First Encounter of Limits
(Reference: TC, 2.2, 2.4, 2.6)
A function f is said to approach the limit L as x approaches
a if f (x) gets arbitrarily close to L for all x suciently close (but not equal) to a.
CHAPTER 2: CONTINUOUS FUNCTIONS
(Reference: TC, 2.5)
A function y = f (x) is continuous if its graph can be drawn with one
continuous motion of the pen.
Let [c, d] be the domain of a function f .
1. f is continuous at an
CHAPTER 3: DERIVATIVES
The Derivative of a Function
(Reference: TC, 3.1, 3.2, 3.3, 3.4)
The slope of the curve y = f (x) at the point P (a, f (a) is the number
f (a + h) f (a)
m = lim
provided the limit exists. The tangent
CHAPTER 7: TECHNIQUES OF INTEGRATION
Integration by Substitution
(Reference: TC, 8.3)
Recall (see 5.4) that by letting u = g(x),
f (g(x)g (x) dx =
This often converts the more complicated integral
f (u) du.
f (g(x)g (x) dx into a simpler integral
CHAPTER 9: FIRST-ORDER DIFFERENTIAL
Separable Dierential Equations
(Reference: TC, 7.4, 9.1)
Goal: To apply calculus to solve dierential equations, which are used to model physical

CHAPTER 6: TRANSCENDENTAL FUNCTIONS
Inverse Functions and Their Derivatives
(Reference: TC, 7.1)
One-to-One Functions and Their Inverses
A function f with domain D is one-to-one if for any x1 , x2 D,
x1 = x2
implies f (x1 ) = f (x2 ).
Chapter 0: Functions
Domain and range of function.
Examples of functions: linear functions, polynomials, rational functions, piecewise
dened functions, trigonometric functions, root functions, logarithmic functions,
CHAPTER 5: INTEGRALS
The Denite Integral
(Reference: TC, 5.1, 5.2, 5.3)
Approximation of Area Under a Graph
Consider the area under the graph of y =
1 x2 , x [0, 1], in the rst quadrant.
Divide the interval [0, 1] into n equal subintervals.

Extreme Values of Functions

Local (Relative) versus Absolute (Global) Extrema
Let f be a function and D be its domain.
1. f has a local maximum (or relative maximum) value at c D
CHAPTER 8: APPLICATIONS OF
Area Between Curves
(Reference: TC, 5.6)
Goal: To use denite integrals to nd areas of regions between curves.
Recall (see 5.1) that for f (x) 0 for all x, the area between y = f (x) and the x-axis
