Slope intercept form is one of the three forms we can use to express a straight line. It is a linear function too; meaning the function can tell you its domain and range. Watch this video tutorial for a full explanation along with examples. [19:10]

Trigonometric equations are just equations that feature the trigonometric ratios such as sine and cosine on the variable "x". Because of the presence of these trigonometric functions, solving these equations becomes a little more difficult. This lesson will show you how to solve first degree trigonometric equations with worked examples and a video. [25:28]

When you see equations in the form of a(x+b) =c, you can remove the bracket and rewrite the equations into ax+ab =c using the distributive property. In this video, you will see how to make use of this property to help solve linear equations. [1:27]

This video will walk you step-by-step through the process of solving one-step linear equations by multiplication and division. [2:39]

You will learn how to solve multi-step linear inequalities in this lesson. Besides typical math questions, you are going to see word problems related to multi-step linear inequalities and money. [8:15]

This video focuses on finding the square of a whole number and the square root of a perfect square. In order to do this, you will first learn how to do prime factorization, a method to find the prime factors of a number. [1:58]

This video tutorial teaches you how to calculate the surface area and volume of cones. Just like pyramids and cylinders, there are formulas for surface area and volume of cones. Also included are questions on composite solids that consist of cones too. Step-by-step explanations are provided along with examples. [3:38]

Graphs of linear relationships are basically just lines and dots. In this video, you will learn the skills to understand and analyze the graphs to get useful information from them. [1:29]

Numbers can be categorized more specifically into different number systems, for instances, natural numbers, whole numbers, integers, rational numbers, and irrational numbers. In this video, you will learn how to classify numbers into different number systems. [3:47]

In the world of calculus, pre-calculus, and trigonometry, you will often find references toward and problems regarding "the unit circle." But, oddly, we are rarely ever taught what it is! This video will change that with an in-depth explanation. [18:16]

When you multiply the same number two times or more, you may express it in exponential form. A number in exponential form has two components, the base and the exponent. This video shows examples of the relationship between repeated multiplication and exponential form. [2:32]
