We review exponents integer and rationalradicals, polynomials, factoring polynomials, rational expressions and complex numbers. After substituting those values into the equation: Easy to use When writing becomes digital At meetings, in lessons, or just at home: Locate another point that lies on the line.

Try to choose numbers that can be graphed on your graph. Absolute Value Inequalities — In this final section of the Solving chapter we will solve inequalities that involve absolute value.

Undetermined Coefficients — In this section we introduce the method of undetermined coefficients to find particular solutions to nonhomogeneous differential equation. The notes are stored in the memory of the receiver in.

Using these notes as a substitute for class is liable to get you in trouble.

We will also introduce the concepts of inconsistent systems of equations and dependent systems of equations. Complex Numbers — In this section we give a very quick primer on complex numbers including standard form, adding, subtracting, multiplying and dividing them.

This is somewhat related to the previous three items, but is important enough to merit its own item. Higher Order Differential Equations - In this chapter we will look at extending many of the ideas of the previous chapters to differential equations with order higher that 2nd order.

As shown above, you can still read off the slope and intercept from this way of writing it. We also define the Laplacian in this section and give a version of the heat equation for two or three dimensional situations.

Factoring Polynomials — In this section we look at factoring polynomials a topic that will appear in pretty much every chapter in this course and so is vital that you understand it.

We will finish off the section with a discussion on parallel and perpendicular lines. As we will see they are mostly just natural extensions of what we already know who to do.

In general, I try to work problems in class that are different from my notes. We will introduce the concept of slope and discuss how to find it from two points on the line.

We also define the Wronskian for systems of differential equations and show how it can be used to determine if we have a general solution to the system of differential equations. Applications of Linear Equations — In this section we discuss a process for solving applications in general although we will focus only on linear equations here.

Writing an Equation Given the Slope and Y-Intercept Write the equation for a line that has a slope of -2 and y-intercept of 5. Linear Equations — In this section we solve linear first order differential equations, i.

This will ensure that your y coordinate is an integer which is much easier to graph.

We also show who to construct a series solution for a differential equation about an ordinary point. Differential Equations Here are my notes for my differential equations course that I teach here at Lamar University. Yes, it is rising; therefore, your slope should be positive!

Hyperbolas — In this section we will graph hyperbolas. We also define the domain and range of a function. We also allow for the introduction of a damper to the system and for general external forces to act on the object. We can get down to business and answer our question of what are the slope and y-intercept.The Digital Pen IRISNotes 3 turns handwritten notes into editable text on your PC, Mac, iOS and Android.

Here is a set of notes used by Paul Dawkins to teach his Differential Equations course at Lamar University.

Included are most of the standard topics in 1st and 2nd order differential equations, Laplace transforms, systems of differential eqauations, series solutions as well as a brief introduction to boundary value problems, Fourier series and partial differntial equations.
