How to Determine the Center of a Circle
Description
A detailed tutorial on how to determine the center of a circle. Step by step tutorial including several examples of the center of a circle for reference.
Overview
The center of the circle is very easy to find. It is one of the endpoints of the radius and the midpoint of the diameter. The video shows you how to find it based on a series of accurate drawing. However, there is a mathematical way to find the center of the circle, which is also sometimes called the origin of the circle. Just use the midpoint formula with the diameter. If you have the radius just multiply it by two, because you cannot use the distance formula without already having the coordinates of the origin.

Overview of Hubble’s Law
Description
A detailed tutorial on Hubble’s law. Step by step tutorial including several examples of Hubble’s law including a visual example for reference.
Overview
Hubble’s law states that the velocity at which various galaxies are receding from the Earth is proportional to their distance from us. This law is often expressed by the equation v = H_0 * D, where H_0 is the constant of proportionality (or Hubble constant) between the distance D to a galaxy and its velocity v.

How to Find Oblique Asymptotes
Description
A detailed tutorial on how to find oblique asymptotes. Step by step tutorial including several examples of how to find oblique asymptotes for reference.
Overview
There are several different types of asymptotes. In this tutorial, we will be discussing oblique asymptotes. In order to find the oblique asymptotes of a function, you must first determine if the asymptote slants. If the numerator of a rational function has exactly one degree greater than the denominator, then the function slants and therefore has an oblique asymptote. When you divide the numerator and the denominator, the term or polynomial you get is the oblique asymptote.

How to Find Horizontal Asymptotes
Description
A detailed tutorial on how to find horizontal asymptotes. Step by step tutorial including several examples of how to find horizontal asymptotes for reference.
Overview
There are several different types of asymptotes. In this tutorial, we will be discussing horizontal asymptotes. In order to find the horizontal asymptotes of a function, take the limit of the function to infinity. Every function has a horizontal asymptote if it has a limit to infinity. The limit is your horizontal asymptote.

How to Find Vertical Asymptotes
Description
A detailed tutorial on how to find vertical asymptotes. Step by step tutorial including several examples of how to find vertical asymptotes for reference.
Overview
There are several different types of asymptotes. In this tutorial, we will be discussing vertical asymptotes. In order to find the vertical asymptotes of a function, we must first determine if there is a vertical asymptote. There is only a vertical asymptote if the limit of the function is equal to positive or negative infinity. If that is true, then the limit will reveal the vertical asymptote.

Introduction to Asymptotes
Description
A detailed tutorial on how to find asymptotes. Step by step tutorial including several examples of how to find asymptotes for reference.
Overview
An asymptote of a curve is a way of describing the behavior of the curve above the origin by comparing it to another curve. The second curve is considered an asymptote of the first if the distance between the two approaches zero as the points themselves extend to infinity. Another way of describing this is that the first curve gets closer to the second as it gets farther from the origin. If the asymptote is a straight line, it is called a linear asymptote.

How to Solve Telegrapher’s Equations
Description
A detailed tutorial on the solving of Telegrapher’s Equations. Step by step tutorial including several examples of how to solve Telegrapher’s Equations for reference.
Overview
Telegrapher’s Equations, sometimes referred to simply as telegraph equations, are a pair of differential equations which meausre the voltage and current on a transmission line with regard to distance and time. An example would be a telegraph, hence the name. Instead of having an actual set of equations, Telegrapher’s Equations tend to more oftenbe expressed as a schematic, with the equations only being used for things such as loops and transmissions.

How to Find the Distance Between Two Points
Description
This video shows how to solve one distance formula problem, with a “solve it yourself” option available. It provides a clear method of solving and easy explanations. The steps are laid out in an easy to follow method.
Overview
Distance is a very common formula in geometry. The formula that is used to solve distance is d = sqrt[(x2 - x1)^2 - (y2 - y1)^2]. In order to use the distance formula, you must be given two points on a graph, represented as (x1, y1) and (x2, y2). You then must plug them in the appropriate places on the distance formula. Continue to solve as you would any basic algebra problem, using the order of operations.
