Definitions are very important to your understanding of why and how we use mathematical processes. Without understanding what a process or certain terms mean it is very hard to understand how or why to do something. That is why I want to...

👉 Learn about and how to apply the remainder and factor theorem. The remainder theorem states that f(a) is the remainder when the polynomial f(x) is divided by x - a. Thus, given a polynomial, f(x), which is to be divided by a linear...

Learn how to divide rational expressions. A rational expression is an expression in the form of a fraction, usually having variable(s) in the denominator. Recall that to divide by a fraction, we multiply by the reciprocal of the...

👉 Learn how to divide a number by the cube root of a non-perfect cube. To divide a number by the cube root of a non-perfect cube, we rationalize the rational number by multiplying both the numerator and the denominator by the cube root...

Master Verifying an identity using the double angle formulas

👉 Learn how to simplify complex fractions. To simplify complex fractions having the addition/subtraction of more than one fractions in the numerator or/and in the denominator we first evaluate the numerator or/and the denominator...

Learn how to determine the initial amount of money to invest compounded continuously

Learn how to add/subtract rational expressions. When adding or subtracting two or more rational expressions with common denominators, we add or subtract only the numerator while we keep the denominator the same. We will then simplify our...

In this video I will derive the Quadratic Formula by Completing the Square to the standard form for a quadratic equation. Have you ever wondered where the quadratic formula came from? Do you struggle to understand why such a...

Wanna know what techniques, innovations, and different elements emerged in Mesopotamia - Time measurement, movement of light.... and How?

In this video, the teacher explains where to place the negative sign in a fraction when dealing with division. They clarify that the negative sign can be placed in the numerator or the denominator, and it will still yield the same answer.

This video explains how to add mixed numbers with like denominators using equivalent fractions. Use area models to visually represent fractions and improper fractions. Review examples and walks through the steps to find equivalent...

👉Learn how to solve quadratic equations using the square root method. It is important to understand that not all quadratics have to be solved using factoring or quadratic formula. When we only have one variable but it is squared we can...

👉 Learn how to solve two-step linear inequalities and graph their solution. When solving two step inequalities we will use inverse operations, reverse order of operations and the properties of equality to solve. We will then graph our...

👉 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 solve literal equations involving formulas. A literal equation is an equation where the unknown values are represented by variables. To solve a literal equation means to make one of the variables the subject of the...

This video provides a fascinating exploration of elephants, the largest land animals on Earth. It delves into their evolutionary history, distinguishing between African and Asian elephants, and highlights their diverse habitats and...

This video provides an overview of the anatomy and feeding habits of spiders. It explains how spiders rely on their eyesight, bristles, and chemical senses to hunt for prey. The video also discusses the structure of a spider's body,...

👉 Learn how to understand the concept of fractions using parts of a whole. Fractions are parts of a whole and this concept can be illustrated using bars and circles. This concept can also be extended to understand equivalent fractions....

👉 Learn how to graph a tangent function. To graph a tangent function, we first determine the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the parent function), the vertical shift (the...

👉 Learn how to convert angles from radians to degrees. Recall that pi radians is equivalent to 180 degrees. Thus, when given an angle in radians, to convert the angle to degrees we multiply the given angle radians by the ratio 180/pi.

How to identify when it is a hole or a fake hole

Divide basic rational expressions fractions

👉 Learn how to evaluate the six trigonometric functions of a given angle. When given an angle we locate the angle on the unit circle. Then using the coordinate of the terminal side of the angle on the unit circle and the definitions of...
