Learn how to add/subtract vectors. Vectors can be added, subtracted and multiplied. To add or subtract two or more vectors, we simply add each of the corresponding components of the vectors.

👉 Learn how to evaluate the limit of a function involving trigonometric expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time....

In this video, students learn how to determine whether a relation is a function by considering tables and graphs. The concept is explained using relatable examples, such as a gumball machine. The video also introduces the use of function...

In this lesson, mathematicians will learn how to model rational functions by graphing. By understanding the relationship between variables in a rational function, students can visually represent the data in tables and graphs. Through...

👉 Learn about the characteristics of a function. Given a function, we can determine the characteristics of the function's graph. We can determine the end behavior of the graph of the function (rises or falls left and rises or falls...

Learn all about ellipses for conic sections. We will discuss all the essential definitions such as center, foci, vertices, co-vertices, major axis and minor axis. We will also discuss the essential processes such as how to graph and...

Learn all about parabolas in conic sections. We will discover the basic definitions such as the vertex, focus, directrix, and axis of symmetry. We will also take a look a basic processes such as graphing, writing the equation and...

👉 Learn how to solve trigonometric equations using the zero product property. The zero product property states that when the product of two quantities is equal to 0, then either of the quantities is zero. When solving factored...

Learn how to add/subtract vectors. Vectors can be added, subtracted and multiplied. To add or subtract two or more vectors, we simply add each of the corresponding components of the vectors.

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a...

The video discusses reciprocal and exponential graphs and their shapes. The instructor explains the formula for reciprocal graphs and how the denominators affect the curve shape. They also cover the negative reciprocal graph and its...

In this video, the teacher explains how to find the area of a polygon by using a key to count the square tiles. The key provides information on how many square units each square tile represents.

Again with the graphs? Yes. Absolutely Yes. Graphs are such an important part of any science, especially physics. The more you work with graphs, the more you will understand them. Here we combine graphs and uniformly accelerated...

In this video, the teacher explains how to choose the appropriate graph to represent data by analyzing its advantages and considering the specific data set. They discuss the advantages of dot plots, histograms, and box plots, and...

Learn how to graph horizontal ellipse which equation is in general form. A horizontal ellipse is an ellipse which major axis is horizontal. When the equation of an ellipse is written in the general form, we first rewrite it in standard...

Learn how to graph a parabola in when it is given in general form. To graph a parabola in conic sections we will need to convert the equation from general form to standard form by completing the square. Once it is in standard form we can...

👉 Learn how to add or subtract two functions. Given two functions, say f(x) and g(x), to add (f+g)(x) or f(x) + g(x) or to subtract (f - g)(x) or f(x) - g(x) the two functions we use the method of adding/subtracting algebraic expressions...
