This video explains how to prove the relationship between the volumes of pyramids and prisms, as well as cylinders and cones, using the Cavalieri principle. The proof involves comparing the volumes of stacked rectangular prisms to the...

In this lesson, students will understand the difference between US customary units and metric units, and how to convert between them. Through examples and practice problems, students will learn how to set up ratio tables and use...

👉 Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph...

👉 Learn how to find the square root of rational numbers. To find the square root of a rational number, we first express the rational number as the square root of the numerator divided by the square root of the denominator and simplify....

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we...

In this video, the teacher explains how to find the scale factor or constant of proportionality in an architect's scale. The concept of ratios, proportions, and scale factors is introduced, and division is used to determine the scale...

In this lesson, students will learn how to determine the exchange rate between two different currencies and use it to convert amounts. They will solve proportions to find the exchange rate and apply it to calculate the amount of one...

In this video, the teacher explains the section formula in coordinate geometry and how it can be used to find the coordinates of a point that divides a line segment in a given ratio. The teacher also introduces the midpoint formula,...

In this video, the teacher explains the logic behind the trigonometric ratio value table for specific angles. Starting with 0 and 90 degrees, the teacher goes on to explain the values for 30, 60, and 45 degrees angles.

During this video lesson we will learn the three ways to write a ratio. We will learn how to determine a rate and a unit rate. We will also learn how to simplify a complex rate to find the unit rate. We will also complete ratio tables...

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we...

We know how to express solution concentration in terms of molarity and molality, but the common public also needs to communicate concentration for certain reasons, and they don't really know about moles and things like that. What do they...

This lesson will cover the patterns of linear, exponential and quadratic functions and review how to determine what type a function from a table of values. We will also review how to write a function rule/equation for a pattern from a...

In this video we will cover the key topics you will need to know before starting our chapter on Trigonometry in Pre-calculus. We will start by working through the Pythagorean Theorem and then working through the trigonometric identities...
