Definition of an even function.
f(-x) = f(x)
Definition of an odd function.
f(-x) = -f(x)
The quadratic formula
x = -B +- sqrt(B^2 - 4AC) / 2A
f is right continuous at c if ?
lim x->c+ f(x) = f(c)
f is left continuous at c if ?
lim x->c- f(x) = f(c)
Open interval = (a, b)
Exclusive point a & b.
Closed interval = [a, b]
Inclusive point a & b.
Linearization approximation of f about is the function L defined by … ?
L(x) = f(a) + f’(a)( x - a )
Taylor’s Formula = ?
Pn(x) = f(a) + f n:th D(a) / n! (x - a)^n
What is the error term called in Taylor’s formula?
LaGrange remainder. f(n + 1)(s) / (n + 1) ( x - a )^(n + 1)
