Exponential and Logarithmic functions Exponential functions Definition Take a > 0 and not equal to 1 . Then, the function defined by f : R -> R : x -> ax is called an exponential function with base a. Graph and properties Let f(x) = an exponential function with a > 1. From the graphs we see that The domain is R The range is the set of strictly positive real numbers The function is continuous in its domain The function is increasing if a > 1 and decreasing if 0 < a < 1 The x-axis is a horizontal asymptote Examples: y = 3x ; y = 0.5x ; y = 100.2x-1 Logarithmic functions Definition and basic properties Take a > 0 and not equal to 1 . are either increasing or decreasing, the inverse functions are defined. loga(x) log10(x) is written as log(x) So, From this we see that the domain of the logarithmic function is the set of strictly positive real numbers, and the range is R. log2(8) = 3 ; log3(sqrt(3)) = 0.5 ; log(0.01) = -2 From the definition it follows immediately that Example: log(102x+1) = 2x+1 Graph log2(x) ; log(2x+4) ; log0.5(x) Thus,

Karl's Calculus Tutor - Box 6.0: Exponential and Log Identities Adding the Exponents: If b is any positive real number then bx by = bx+y for all x and y. This is the single most important identity concerning logs and exponents. Since ex is only a special case of an exponential function, it is also true that ex ey = ex+y Multiplying the Exponents: If b is any positive real number then (bx)y = bxy for all x and y. (ex)y = exy Converting to roots to exponents: The nth root of x is the same as x1/n for all positive x. _ √x = x1/2 In addition: __ √ex = ex/2 Converting to ex form: If b is any positive real number then bx = ex ln(b) for all x. xx = ex ln(x) or if you have f(x)x: f(x)x = ex ln(f(x)) or if you have xf(x): xf(x) = ef(x) ln(x) or if you have f(x)g(x): f(x)g(x) = eg(x) ln(f(x)) As an example, suppose you had (x2 + 1)1/x. e(1/x) ln(x2 + 1) ex is its own derivative: The derivative of ex is ex. ex is always positive: You can put in any x, positive or negative, and ex will always be greater than zero. logb(xy) = logb(x) + logb(y) This includes k logb(x) = logb(xk) and
The AP Calculus BC Exam Exam Content In 1956, 386 students took what was then known as the AP Mathematics Exam. By 1969, still under the heading of AP Mathematics, it had become Calculus AB and Calculus BC. The Calculus BC exam covers the same differential and integral calculus topics that are included in the Calculus AB exam, plus additional topics in differential and integral calculus, and polynomial approximations and series. This is material that would be included in a two-semester calculus sequence at the college level. If students take the BC exam, they cannot take the AB exam in the same year because the exams share some questions.

Differential Equations Differential Equations (Math 3301) Here are my online notes for my differential equations course that I teach here at Lamar University. Despite the fact that these are my “class notes”, they should be accessible to anyone wanting to learn how to solve differential equations or needing a refresher on differential equations. I’ve tried to make these notes as self contained as possible and so all the information needed to read through them is either from a Calculus or Algebra class or contained in other sections of the notes. A couple of warnings to my students who may be here to get a copy of what happened on a day that you missed. Because I wanted to make this a fairly complete set of notes for anyone wanting to learn differential equations I have included some material that I do not usually have time to cover in class and because this changes from semester to semester it is not noted here. Here is a listing and brief description of the material in this set of notes. Basic Concepts

Calculus III - Higher Order Partial Derivatives Just as we had higher order derivatives with functions of one variable we will also have higher order derivatives of functions of more than one variable. However, this time we will have more options since we do have more than one variable.. Consider the case of a function of two variables, since both of the first order partial derivatives are also functions of x and y we could in turn differentiate each with respect to x or y. The second and third second order partial derivatives are often called mixed partial derivatives since we are taking derivatives with respect to more than one variable. , then we will differentiate from left to right. , it is the opposite. Let’s take a quick look at an example. Notice that we dropped the from the derivatives. Now let’s also notice that, in this case, . Clairaut’s Theorem Now, do not get too excited about the disk business and the fact that we gave the theorem for a specific point. So far we have only looked at second order derivatives. .
