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

👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves...

Historically, election season leads to a volatile market. Here's what that means for your investments.

How does the weather affect your mood? There's a common thought around the world that sunny warm weather is linked to happiness and cold cloudy weather is linked to sadness. But is there any science behind this idea? Does the weather...

In this video, the speaker discusses the importance of passion and relevance in becoming an excellent trainer. They share four steps to improve training skills, including inspiring and ensuring relevance, using engaging activities,...

In this video, we compare the slopes and y-intercepts of different functions to understand how they are alike and different. By examining graphs and tables of values, we observe how the scaling affects the position of the functions in...

👉 How to write the rule of a function given the table of values. To write the rule of a function from the table is somehow tricky but can be made easier by having prior knowledge of the type of function. If the function is a linear...

👉 Learn how to evaluate the limit of a function involving rational 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. The...

In this video lesson, students will learn how to add integers with the same sign by analyzing the rules using a number line. The teacher explains the concept of absolute value and emphasizes the importance of moving in the correct...

In this video, students learn about quadrants and how they relate to coordinate planes. The video explains how to determine the quadrant of a point by examining the values of an ordered pair. It also introduces the concept of UPS (Unique...

This video explains the concept of integers and addition, and demonstrates how to graphically represent the addition of positive and negative numbers on a number line. Through clear examples and step-by-step instructions, students will...

👉 Learn how to evaluate the limit of a function involving rational 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. The...

👉 Learn how to determine the concavity of a function. A function is said to be concave up (convex) if the graph of the curve is facing upwards and the function is said to be concave down (concave) if the graph is facing down. To test for...

👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves...

The U.S. economy is on a roll, setting the pace for global growth. How long can that continue? And what should we make of the rising U.S. budget deficit?

👉 Learn how to find all the zeros of a polynomial. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. The zeros of a polynomial are the values...

👉 Learn how to write the equation of a polynomial when given rational zeros. Recall that a polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. The...

In this lesson, your instructor David, examines integers; signed and unsigned, how large or small they can be, and what happens if they exceed these limits.

👉 Learn how to use the double angle identities to solve trigonometric equations. When we have equations with a double angle we will apply the identities to create an equation that can help solve by inverse operations or factoring. We...

How to understand reflections of polar points

👉 Learn how to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a definite...

👉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...

Shear and Bending are internal forces and moments that can be calculated by making cut sections along different sections of a beam. In general, the shear force and bending moment can vary along the length of the beam x, which is why we...

David Tuckett explores the role emotions play in asset management and the role of psychological phenomena, such as rationalization and group think, in market activity. While good statistical research can help you make good decisions, he...
