In this lesson, students will learn how positive and negative numbers are used to measure elevation above and below sea level. They will understand that sea level represents 0 elevation, and that both positive and negative elevations...

In this video, students will learn how to subtract integers by using the take away definition of subtraction on a number line. The video explains what integers are, what subtraction is, and how to interpret subtraction as taking away or...

Learn how to create slope fields and sketch the particular solution to a differential equation. Slope fields are tools used to graphically obtain the solutions to a differential equation. It is the estimation of the graphical...

In this lesson, students will learn how to solve multistep word problems involving positive and negative decimals using mathematical reasoning. They will be guided through an example problem where a student named Henry wants to purchase...

👉 Learn all about evaluating trigonometric functions with triangles. In this playlist, we will learn how to evaluate, sine, cosine, tangent, cotangent, secant, and cosecant when given the sides of a triangle. If we have missing sides we...

👉 Learn how to solve equations using the angles sum and difference identities. Using the angles sum and difference identities, we are able to expand the trigonometric expressions, thereby obtaining the values of the non-variable terms....

👉 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...

The video discusses the topic of labor markets, specifically the impact of a higher minimum wage on the economy. The video analyzes the factors that affect the significance of this trade-off, such as the size of cash reserves that...

👉 Learn how to find the domain of a radical function. Recall that the domain of a function is the set of possible input values (x-values) of the function. For a radical square-root function, there cannot be a negative number inside the...

👉 Learn how to write the rule of a sequence given a sequence of numbers. 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. To write the explicit formula of...

👉 Learn how to evaluate the limit of a function by rationalizing the radical. 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 limit...

👉 Learn how to solve quadratic equations using the quadratic formula. A quadratic equation is an equation whose highest power on its variable(s) is 2. The quadratic formula is a formula which can be used to find the roots of (solve) a...

The video discusses the importance of scenario planning for businesses in responding to uncertainty and unexpected events that may disrupt their projections and performance. The presenter discusses the various types of risks that...

Conservation of charge is defined. Two common example problems are solved. The common mistake of forgetting about charge conservation is shown. Excess number of charge carriers is determined.

👉 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...

This video explains the concept of bank rates and the transmission mechanism, which is the process by which a central bank's monetary policy decisions are passed on through financial markets to businesses and households. The video covers...

Peter Quarry and Eve Ash recommend techniques for recognizing and unblocking low motivation, identifying a sense of purpose (the Five Whys), improving leadership and people’s feelings of being appreciated.

In this video, students will learn how to graph sinusoidal functions by plotting points and observing the terminal ray of the unit circle. They will understand the patterns and periodicity of the sine and cosine functions, and how to...

👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry,...

This is the first part of the first torque problem about the elbow joint in which we calculate the force due to the elbow flexors (biceps brachii) and the mechanical advantage of the elbow.
