Triangle Classifications Our study of triangles begins with their different classifications. But before we can do this, we must learn how to name triangles. Since triangles are defined by their three vertices, we use the triangle symbol, ?, followed by the three vertices (in any order). For instance, ?

Algebra "Algebraist" redirects here. For the novel by Iain M. Banks, see The Algebraist. Solving Equations-steps To perform these steps you will need to use a number of mathematical properties of addition, subtraction, multiplication, and division. The use of these properties, both in combining like terms and isolating terms and variables, will be reviewed in this unit. In the next unit we will solve equations containing two variables, called multivariate equations. Step 1: Combine Like Terms As we learned in the last unit, like terms are terms that contain the same variable or group of variables raised to the same exponent, regardless of their numerical coefficient.

Calculus I - Definition of the Definite Integral In this section we will formally define the definite integral and give many of the properties of definite integrals. Let’s start off with the definition of a definite integral. Definite Integral The definite integral is defined to be exactly the limit and summation that we looked at in the last section to find the net area between a function and the x-axis. Combining Like Terms A frequently-used procedure in algebra is the process of combining like terms. This is a way to "clean-up" an equation and make it much easier to solve. In case you've forgotten, a term is each single part of an expression. For example, in the expression 4x + 3 + 7y, there are three terms: 4x, 3, and 7y. The number 4 is not a term, but rather a factor of the term 4x.

Trig without Tears: Contents Summary: Faced with the large number of trigonometric identities, students tend to try to memorize them all. That way lies disaster. When you memorize a formula by rote, you have no way to know whether you’re remembering it correctly. I believe it is much more effective (and, in the long run, much easier) to understand thoroughly how the trig functions work, memorize half a dozen formulas, and work out the rest as needed. That’s what these pages show you how to do. The Standards Building on the best of existing state standards, the Common Core State Standards provide clear and consistent learning goals to help prepare students for college, career, and life. The standards clearly demonstrate what students are expected to learn at each grade level, so that every parent and teacher can understand and support their learning. The standards are: Research and evidence basedClear, understandable, and consistentAligned with college and career expectationsBased on rigorous content and the application of knowledge through higher-order thinking skillsBuilt upon the strengths and lessons of current state standardsInformed by other top-performing countries to prepare all students for success in our global economy and society
