Geometric Proofs, Part 3

In this video, the teacher explains how to solve a quadratic equation that has no real solutions using the quadratic formula. The video also covers a review of imaginary and complex numbers, as well as a common mistake to avoid when...

In this video, we explore the concept of closed and open sets of numbers. We learn that a set is closed under an operation if applying that operation to any two members of the set always results in a member of the set. We also discover...

In this lesson, students will learn about square roots and how to place them between two integers on a number line. They will understand that numbers that are not perfect squares still have square roots, and they will be able to estimate...

👉 Learn how to add or subtract two functions. Given two functions, say f(x) and g(x), to add (f+g)(x) or f(x) + g(x) or to subtract (f - g)(x) or f(x) - g(x) the two functions we use the method of adding/subtracting algebraic expressions...

The velocity as a function of position of a horizontal mass-spring system is derived, graphed, and demonstrated. This is an AP Physics C: Mechanics topic. Content Times: 0:00 Simple Harmonic Motion Review 0:34 Total Mechanical Energy...

This video lesson teaches students how to solve quadratic equations using the quadratic formula. It explains the concept of finding where a quadratic crosses the x-axis and how to set up the equation to find the solutions. The video also...

What is the maximum linear speed a car can move over the top of a semi-circular hill without its tires lifting off the ground? The radius of the hill is 1.8 meters.

This video is about physics vs math and how to know which major is right for you. You may have enjoyed them both in high school so of course you may want to major in one in college.



The good news is that if you major in...

Before the method of completing the square was developed, only very limited types of quadratic equations could be solved. This method eliminated those limitations, allowing the solutions of any quadratic equation to be found. As...

Learn how to eliminate the parameter in a parametric equation. A parametric equation is a set of equations that express a set of quantities as explicit functions of a number of independent variables, known as parameters. Eliminating the...

In this lesson, students will learn about horizontal scaling of quadratic equations. They will explore how the functions F of X, G of X, and H of X are alike and different, and how the value of "a" in the vertex form of the equation...

In this video, the teacher explains how to find the height of a building and the length of a television using the Pythagorean theorem. They review the formulas for the theorem and demonstrate how to round square roots to the nearest...

In this video, mathematicians learn how to find the center and radius of a circle by analyzing its equation. The video explains the key components of a circle, such as the center and radius, and then breaks down the standard form of a...

👉 Learn how to find the derivative of a function using the power rule. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process of finding the derivative...

This video continues the exploration of a three dimensional Cartesian coordinate system.This video covers two basic examples requiring the use of the distance formula in three dimensions. In addition, the equation of a sphere is also...

Learn how to solve the particular solution of differential equations. A differential equation is an equation that relates a function with its derivatives. The solution to a differential equation involves two parts: the general solution...

👉 Learn how to add or subtract two functions. Given two functions, say f(x) and g(x), to add (f+g)(x) or f(x) + g(x) or to subtract (f - g)(x) or f(x) - g(x) the two functions we use the method of adding/subtracting algebraic expressions...

In this introductory free-fall acceleration problem we analyze a video of a medicine ball being dropped to determine the final velocity and the time in free-fall. Included are three common mistakes students make. "Why include...

This video goes over two examples, covering the proper way to find definite integrals that require the use of multiple integration techniques. Specifically, integration by parts and u-substitution.

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips. I believe everyone can learn math...

Learn how to use the Conservation of Mechanical Energy equation by solving a trebuchet problem.
