Using R, Chapter 6: Normal Distributions pnorm and …

1. Using R, Chapter 6: Normal Distributions The pnorm and qnorm functions . Getting probabilities from a Normal distribution with mean and standard deviation . pnorm (x, mean = , sd = , ). If x is a normally distributed random variable, with mean = and standard deviation = , then P (x < xmax ) = pnorm (xmax , mean = , sd = , ). P (x > xmin ) = pnorm (xmin , mean = , sd = , ). P (xmin < x < xmax ) = pnorm (xmax , mean = , sd = , ). - pnorm (xmin , mean = , sd = , ). Examples: Suppose IQ's are normally distributed with a mean of 100 and a standard deviation of 15.

Definitions of the Inverse Functions When the trig functions are restricted to the domains above they become one-to-one func-tions, so we can define the inverse functions. For the sine function we use the notation sin−1(x) or arcsin(x). Both are read “arc sine” . Look carefully at where we have placed the -1.

2 Complex Functions and the Cauchy-Riemann Equations

www.math.columbia.edu

We can de ne a broader class of complex functions by dividing polynomi-als. By de nition, a rational function R(z) is a quotient of two polynomials: R(z) = P(z)=Q(z); where P(z) and Q(z) are polynomials and Q(z) is not identically zero. Using the factorization (1) above, it is not hard to see that, if R(z) is not actually

Chapter 2: 2.1 Functions: definition, notation A function is a rule (correspondence) that assigns to each element x of one set , say X, one and only one element y of another set, Y. The set X is called the domain of the function and the set of all elements of the set Y that are associated with some element of the set X is called the range of the function.

Let f : R → R` be the identity function f(x) = x (which is of course continuous when mapping R → R). Then f is not continuous here since for a < b, [a,b) is open in R` for f−1([a,b)) = [a,b) is not open in R. Note.

Exponential Functions with Base e

Exponential Functions with Base e. Any positive number can be used as the base for an exponential function, but some bases are more useful than others. For instance, in computer science applications, the base 2 is convenient. The most important base though is the number denoted by the letter e.
