Welcome to She Loves Math! Symmetry — In this section we introduce the idea of symmetry. We will solve linear as well as nonlinear systems of equations. Systems of Equations - In this chapter we will take a look at solving systems of equations.

Recall that these points will be the only place where the function may change sign. A nonlinear system of equations is a system in which at least one of the equations is not linear, i. Applications of Quadratic Equations — In this section we will revisit some of the applications we saw in the linear application section, only this time they will involve solving a quadratic equation.

Put in numbers and try it! And, even better, a site that covers math topics from before kindergarten through high school. You plan to sell She Love Math t-shirts as a fundraiser. Now, I just have to reprint that one and laminate it. She even links to files so you can recreate them yourself!

I started off by asking students what the cheapest way to get a burger, fries, and a drink were at a fast food restaurant. Now, onto perfect cubes! Apparently fritos are gross. We will concentrate on solving linear inequalities in this section both single and double inequalities. All throughout a calculus course we will be finding roots of functions.

Parabolas — In this section we will be graphing parabolas. The first time I printed these I got the colors off. Polynomials — In this section we will introduce the basics of polynomials a topic that will appear throughout this course.

Equations With More Than One Variable — In this section we will look at solving equations with more than one variable in them. Note as well that order is important here.Here is a set of notes used by Paul Dawkins to teach his Algebra course at Lamar University.

Included area a review of exponents, radicals, polynomials as well as indepth discussions of solving equations (linear, quadratic, absolute value, exponential, logarithm) and inqualities (polynomial, rational, absolute value), functions (definition, notation, evaluation, inverse functions) graphing.

Math homework help. Hotmath explains math textbook homework problems with step-by-step math answers for algebra, geometry, and calculus. Online tutoring available for math help.

Quickly coming backing to the example mentioned a second ago, graphing y=-4|x| is as simple as starting at the origin (because there's no numbers being added or subtracted on the inside or the.

Pre-algebra and algebra lessons, from negative numbers through pre-calculus. Grouped by level of study.

Lessons are practical in nature informal in tone, and contain many worked examples and warnings about problem areas and probable "trick" questions.

Piecewise Functions A Function Can be in Pieces. We can create functions that behave differently based on the input (x) value. A function made up of 3 pieces.

Example: when x is less than 2, it gives x 2, when x is exactly 2 it gives 6.
