In this video, students learn about reflecting a parallelogram and how it affects the shape. The teacher explains the concept using vocabulary terms such as congruent line segments, congruent angles, and parallel lines.

Johnson officially resigned as Prime Minister last week, so we wanted to take some time to reflect on his tenure. From how Johnson ended up in Number 10 to why he eventually saw his grand vision come crumbling down.

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 1HR Q5, which involves a quadratic expression and prime numbers. Students will review prime numbers, as well as the properties of quadratic...

This video discusses the concept of real numbers and how they can be represented on a number line. It covers whole numbers, integers, prime and composite numbers, rational and irrational numbers, and how they all form the set of real...

The Mathematics of Cryptography

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

👉 Learn how to factor a number, variable, and monomial completely. To factor means to write our term as a product of its factors. Therefore we will learn how to break down a number, variable, and monomial into its factors.

👉 Learn how to factor a number, variable, and monomial completely. To factor means to write our term as a product of its factors. Therefore we will learn how to break down a number, variable, and monomial into its factors.

In this video, the teacher explains how to dilate a triangle without using a graph. They review the concept of scale factor and show how it affects the dimensions of an image. By multiplying the coordinates of each point by the scale...

👉 Learn how to evaluate the limit of a function using the difference quotient formula. The difference quotient is a measure of the average rate of change of the function over an interval, h. The limit of the difference quotient gives the...

👉 Learn how to factor a number, variable, and monomial completely. To factor means to write our term as a product of its factors. Therefore we will learn how to break down a number, variable, and monomial into its factors.

This is an educational video discussing the unique factorization theorem, which states that any number can be written as the product of its prime factors. The video goes in-depth to explain what prime factors are and how to decompose a...

This video goes over 3 examples, covering the proper way to use the integration by parts formula. This video includes an example covering the two forms of the integration by parts formula, an example where rewriting of the integrand is...

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

👉 Learn how to apply transformations such as translations, rotations, reflections as well as dilation to points, lines, triangles, and other shapes. When applying transformations we will use certain rules as well as tricks to help you...

👉 Learn how to find the derivative of a function using the quotient 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...

👉 Learn how to find the derivative of the inverse of a function. 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 of a...

In this playlist I show you how to understand set theory. I introduce sets as Venn diagrams, mapping and as sets of numbers. With sets we look at how to find the union, compliment, and intersection of given sets. We introduce sets with...

This nugget describes historical aspect of discovery of nucleic acid, basic structure of polynucleotide chain, Watson model of DNA and types of DNA.

In this video, the teacher explains how to describe the intersection of two events. The examples used include rolling a die and surveying students' activities. The teacher emphasizes that the intersection of events consists of outcomes...

In this video, the teacher explains the concept of rotational congruence in geometry. They demonstrate how to determine if two shapes are congruent by examining the distance of points from the origin and the measure of angles formed.

👉 Learn how to apply transformations of a figure and on a plane. We will do this by sliding the figure based on the transformation vector or directions of translations. When performing a translation we are sliding a given figure up,...
