👉 Learn how to write the explicit formula for the nth term of an arithmetic sequence. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. An arithmetic...

In the previous tutorial we introduced our second quantum problem, that of the quantum barrier potential. Again, this involves a free particle that encounters a barrier of finite potential. We've already solved the Schrödinger equation...

In this video, the teacher explains how to multiply a mixed number by a mixed number using visual representations. The example used is finding the area of a vegetable garden. The teacher demonstrates how to draw boxes to represent the...

Subtracting Functions and finding the domain in interval notation

👉 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...

👉 Learn how to solve multi-step linear inequalities having no parenthesis. An inequality is a statement in which one value is not equal to the other value. An inequality is linear when the highest exponent in its variable(s) is 1. (i.e....

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

👉 Learn how to verify trigonometric identities by expanding the trigonometric expressions. When the given trigonometric expressions involve multiplications with more than one term in parenthesis, we start by expanding the expressions...

👉 Learn how to verify trigonometric identities involving the addition and subtraction of terms. To do this it is usually useful to convert the addition or subtraction terms in terms of one trigonometric function and then evaluate....

👉In this video I will work through 22 different examples of solving two step equations using a worksheet I created for my students. I will use the properties of equality, inverse operations and reverse order...

In this math tutorial I will show you how to add and subtract complex numbers. You will learn the steps in adding rational complex numbers and rational expressions with imaginary. Like polynomials when adding complex numbers we can only...

In this video, the teacher explains how to write equations of lines in point slope form using a given point and slope or two given points. The video also covers how point slope form relates to slope and how to convert point slope form to...

👉In this video I show you the major mistakes I see students make when solving linear equations with fractions. This involves using inverse operations and using the LCD/LCM Timestamps: 0:00 Intro 0:23 Simple one step equation ex 1 1:01...

👉 Learn how to solve two step linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. To solve for a variable in a two step linear equation, we first isolate the variable by using inverse...

👉 Learn how to add or subtract fractions with common denominators. When adding or subtracting two or more fractions with common denominators, we add or subtract only the numerator while we keep the denominator the same. We will then...

In this video series I will show you how to add and subtract rational expressions. When adding and subtracting fractions it is important for us only to combine terms when they have the same denominator. This holds true for rational...

In this video lesson we will learn that we use the same rule for subtracting rational numbers as we did for subtracting integers. We will rewrite the subtraction problem to be an addition problem by adding the opposite value. Fondly...

👉 Learn how to solve two step linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. To solve for a variable in a two step linear equation, we first isolate the variable by using inverse...

👉 Learn how to simplify rational identities involving addition and subtraction. To simplify rational identities involving addition and subtraction, first, we find the LCM of the denominators which most time is the product of the terms in...
