In this video I explain the three shifters of the money supply. Pay attention, you'll need this to learn monetary policy. Thanks for watching.

In this video, the teacher explains how to interpret the rate of change and the Y intercept in different contexts. Using examples such as an emptying pool and a traveling car, the teacher demonstrates how to understand the meaning behind...

This video explains the concept of rates of change and how it is represented graphically through the gradient of a line. The video also demonstrates how to calculate the gradient using the change in Y divided by the change in X or Y...

This video explains how to write an equation that represents the proportional relationship between distance and time. Review how to find the unit rate by dividing the total distance by the total time. The teacher also clarifies that when...

👉 Learn how to solve proportional rate problems using integration. 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...

👉 Learn how to solve particle motion problems. Particle motion problems are usually modeled using functions. Now, when the function modeling the position of the particle is given with respect to the time, we find the speed function of...

This is a tutorial on how to use the SUMPRODUCT function in Microsoft Excel for row level calculations. The function performs both multiplication and addition and can be used for text searches and cell references. The tutorial provides...

👉 Learn how to solve proportional rate problems using integration. 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...

The video is a presentation on the problem theorem of calculus, which explains the link between integration and differentiation. The speaker begins by reviewing differentiation and integration, and how they relate to each other. The...

The video is a lecture on acceleration and how we quantify the rate of change of an object's velocity. The presenter discusses the concept of acceleration, how it is measured, and the equation used to calculate it. Examples are provided...

The video discusses the main factors that influence the level of consumption and spending patterns within an economy. The presenter explains the concept of consumption, which represents the total amount of money that households spend on...

In this video, we explain the different ways a linear function can be represented and focus on the components of the equation y = mx + b. We demonstrate how to find the y-intercept (b) and the slope (m) by using rise over run. The...

This video explains how to graph a line using a point on the line and the slope of the line. The concept of function notation and slope is reviewed. This method is applied to estimate the time it will take to travel a certain distance in...
