Let's learn more about one significant measure to determine how well our regressions work using the coefficient of determination.

In this video, we will look at the impact of the data changes we make with underlying data in the measures of central tendency or dispersion.

Explore the physics of a double-star system: calculate the angular speed of two orbiting stars and determine the minimum escape speed a meteoroid needs to flee the gravitational pull from the center of mass.

A video entitled "Find Surface Area: Cylinder" which shows how to calculate the surface area of a cylinder using the formulas for area of a circle and area of a rectangle.

Short video describing acceleration - for middle school

A video entitled "Testing a Model" which shows how to use the Chi-Square Test.

In a poll of the 50 of the most respected scientists, only one man was on every list at or near the top - Greatest scientist of all time. The birth of physics starts: Isaac Newton had many...

Howcast - Learn how to cut and shape nails from Spa Taxi owner Danielle Corbin Jaime in this Howcast nail tutorial.

Factoring is the opposite of distributing. If you can find a common factor, you can reduce an expression.

Pupil outcome: I can identify and use square numbers to solve problems Key learning points: - A square number of objects can be arranged into a square array. - A square number can be represented as the product of two factors which are...

This video explains how to calculate angular displacement and other rotational kinematic variables for a rotating wheel, illustrating concepts like angular acceleration and revolutions.

This content analyzes the motion of a solid cylinder rolling down an inclined roof. It uses the conservation of energy to determine the angular speed as it leaves the roof and then applies projectile motion principles to calculate the...

In this video, we do a quick few examples of factoring trinomials. To get a more conceptual understanding of why factoring by grouping works, please watch my other video: • Factor Polynomials by Grouping

In this video, we factor polynomials with long division. Specifically, we look at examples where there is a "missing term," and we discover how to rewrite the polynomial so that it factors nicely.

In this video, we will factor polynomials that don't initially appear to be in the form of a quadratic. We will accomplish this by rewriting them in the form of a quadratic with substitution.

In this video, we factor special product binomials. Specifically, we factor difference of square, sum of cubes, and difference of cubes.

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video, we learn how to add, subtract, multiply, and divide complex numbers. In the dividing portion of this video (7:05), we look at how to use the complex conjugate to rewrite quotients.

In this video, we use substitution to take equations and rewrite them in the form of a quadratic so that we can solve them.

In this video, we find the difference quotient for two different functions.

In this video, we add and subtract rational expressions by finding the common denominator.

This video discusses center-radius form of a circle. There are multiply ways to write the equation of the circle, but this is the most common form of it. In order to write this equation, you only need to know the center (h,k) and the...

In this video, we will use the equation of a circle to find the center and radius.

In this video, we learn how to use composite functions (function composition) in a real-world problem.
