Lecture 22: The Denite Integral (Sections 5.2, 5.3)
Denition
If f is dened and continuous for a x b , we divide [a, b ] into n
subintervals of equal width x = (b a)/n. Let
x0 (= a), x1 , x2 , . . . ,
Lecture 29: Integration by Parts (Section 8.1)
Recall the Product Rule for dierentiation
Product Rule
If f and g are dierentiable functions, then
(fg ) = f g + fg
This implies
f (x )g (x ) dx +
g (x )
Lecture 24: Inverse Functions (Section 7.1)
Denition
A function f is called one-to-one if it never takes on the same value
twice, that is,
f (x1 ) = f (x2 )
whenever x1 = x2
Example 1: Is f (x ) = x 2
Lecture 15: Maximum and Minimum (Section 4.1)
Denition
A function f has an absolute maximum at x = c if
f (c ) f (x )
for all x D . f (c ) is the maximum value of f on D.
Denition
A function f has an
Lecture 8: Derivatives (Sections 3.1, 3.2)
Denition
The tangent line to the curve y = f (x ) at the point P (a, f (a) is the
line through P with slope
f (x ) f (a)
x a
x a
m = lim
if this limit exists
Lecture 5: Limits
Sections 2.1 & 2.2
Example 1: Find an equation of the tangent line to y = x 2 + 1 at the
point P (1, 2).
We know that the equation of this line is
y 2 = m(x 1)
where m is its slope.
Lecture 3: Elementary Functions
Denition
A function f is a rule that assigns to each element x in a set D exactly
one element, called f (x ) in a set E .
D = the domain of f
E = the range of f
We can
