Solving Trigonometric Equations Part 2

This is part 2 of 2 on Solving Trigonometric Equations (see Solving Trigonometric Equations Part 1 for problems 1 to 5). In this tutorial I will solve several different trigonometric equations using different techniques such as factoring, substitution and converting the equation to all one trigonometric function using identities. Solving trigonometric equations involves knowledge of…

Solving Trigonometric Equations Part 1

This tutorial is Part 1 of 2 on Solving Trigonometric Equations. In this tutorial I will solve several different trigonometric equations using different techniques such as factoring, substitution and converting the equation to all one trigonometric function using identities. Solving trigonometric equations involves knowledge of several mathematical concepts such as factoring techniques we learn in…

Solving a Two-Step Equation

SOLVING TWO-STEP EQUATIONS • Your objective is to get the variable isolated on one side and then get it all alone. Also, Remember whatever you do to one side you must do the other. This requires two steps. • Definitions -A Variable is a letter of the alphabet that represents a number -A Constant is…

Getting Ready for Algebra

Below are some tips that you can take starting today to prepare for your first college level math course. First, understand that you will need to take the Accuplacer test. After you are admitted contact a representative from your college or university. Usually this is a representative in the Office of Student Retention or Student…

The Chain Rule (Simple)

Here, I will be talking about how to find the derivative of a function using The Chain Rule. To start off, I’ll remind you, or tell you, what the derivative is. The derivative of a function is the rate of change of that function at the given point. This is also known as the slope…

Basic derivatives (The power rule)

Differentiating can be a pretty daunting task. Although there are many different rules to follow for more advanced problems, the power rule is the basic rule of derivatives. The derivative of a function provides the equation of the slope of the original function. Each point on the derivative graph gives the instantaneous rate of change…

Naming Decimal Places

Write the name of each decimal place indicated with a line under the number.

Triangle Inequalities: Can it Make a Triangle?

There are rules that triangles must follow. One of these rules is that the sum of the lengths of any two sides of a triangle is greater than the length of the 3rd side. In other words, whenever you add the length of two sides of a triangle together, it must equal more than the…

The Chain Rule

How do we differentiate F(x)=Tan(2x-4)? This function is the composite FoG of two functions F (u)=Tan u and u=2x-4 that we know how to differentiate. The Chain rule states that the correct answer to F(x) is derived by multiplying the derivatives of F and G.

Partial Fraction Decomposition w/ Substitute Numerators

Partial Fraction Decomposition: the process of starting with the simplified answer and taking it back apart, or “decomposing” the final expression into its initial polynomial fractions. With this tutorial, you’ll learn how to set up an equation that will help you to solve problems like these.
