As already noted not everything in these notes is covered in class and often material or insights not in these notes is covered in class. This form is the best way to find the slope and y intercept of a linear equation, where m is the slope and b is the y intercept.
This graph will be a horizontal line. There are an infinite number of solutions for this graph, as the line goes on forever in both directions. Solving Equations and Inequalities - In this chapter we will look at one of the most important topics of the class.
Notice that A 0,0 is the origin because both it's x and y values are 0. Due to the nature of the mathematics on this site it is best views in landscape mode. You should always talk to someone who was in class on the day you missed and compare these notes to their notes and see what the differences are.
In particular we will model an object connected to a spring and moving up and down. This makes y the dependent variable, which means that it is dependent on how x is being changed. We will solve linear as well as nonlinear systems of equations.
Here is an expression When we plug in different values of x, we also yield a different output as well. Eigenvalues and Eigenvectors — In this section we will introduce the concept of eigenvalues and eigenvectors of a matrix.
In particular we will look at mixing problems modeling the amount of a substance dissolved in a liquid and liquid both enters and exitspopulation problems modeling a population under a variety of situations in which the population can enter or exit and falling objects modeling the velocity of a falling object under the influence of both gravity and air resistance.
Now you are going to learn about slope and y-intercepts to make graphing these equations much easier and quicker. We will also work a few examples illustrating some of the interesting differences in using boundary values instead of initial conditions in solving differential equations.
Here is a listing and brief description of the material that is in this set of notes. We will use reduction of order to derive the second solution needed to get a general solution in this case. Laplace Transforms — In this section we introduce the way we usually compute Laplace transforms that avoids needing to use the definition.
We will also develop a formula that can be used in these cases.
This is where the point is located. 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.
Any point on this line is a solution to the equation. Symmetry — In this section we introduce the idea of symmetry. Finally, let's plug in -1,1. The rate is your slope in the problem.
We can also find other solutions for the equation just by reading the graph. Remember, you also have a choice of positive or negative numbers. The graph will be concave down if the second derivation of the equation describing it is a negative constant.
Convolution Integral — In this section we giver a brief introduction to the convolution integral and how it can be used to take inverse Laplace transforms. This is another true statement, so 1,1 is a solution to the equation. Once we have the eigenvalues for a matrix we also show how to find the corresponding eigenvalues for the matrix.
Every point on that line is a solution to the equation. At this point in my career I mostly teach Calculus and Differential Equations. Scientiﬁc Writing for Computer Science Students Wilhelmiina H¨am¨al¨ainen Course material September 20, Department of Computer Science University of Joensuu.
