Holly Whitaker, author of "Quit Like A Woman," explains how to recalibrate your relationship with alcohol in a post-Covid world.

This video explains how objects orbit other objects in space, with a focus on natural and artificial satellites. The video starts by discussing Earth's orbit around the sun and how the gravitational force of the sun causes the Earth to...

This video is a presentation on graphs and their reciprocal values. The presenter begins by defining the reciprocal as one over a number and then works out values to demonstrate how the reciprocal changes as the value of X changes. The...

Characteristics of Functions

👉 Learn how to determine the end behavior of the graph of a polynomial function. To do this we will first need to make sure we have the polynomial in standard form with descending powers. We will then identify the leading terms so that...

Sea level rise is often spoken of in future terms, including projections for impacts we’re likely to see by the end of the century. But in many communities in the U.S., sea level rise is already a factor in people’s lives in the form of...

In this Microsoft Excel tutorial, we will learn six different methods to change the width and height of cells. These methods include using the mouse to adjust the size, using keyboard shortcuts, using the double-click feature, selecting...

👉 Learn how to determine increasing/decreasing intervals. There are many ways in which we can determine whether a function is increasing or decreasing but we will focus on determining increasing/decreasing from the graph of the function....

J. Doyne Farmer, professor at the Santa Fe Institute, says that the core ideas in economics will shift entirely within 25 years. And this can already be seen: economists, he says, are even now studying issues like "what makes people...

Is there a pause in global warming?



There's not really a pause in global warming. Sometimes there's natural fluctuations and we warm up a little faster in one decade and a little slower in another decade, but global warming,...

👉 Learn how to determine increasing/decreasing intervals. There are many ways in which we can determine whether a function is increasing or decreasing but we will focus on determining increasing/decreasing from the graph of the function....

👉 Learn how to graph exponential functions. An exponential function is a function that increases rapidly as the value of x increases. To graph an exponential function, it is usually very useful to make the table of values of the...

An introduction to related rates.

Loops - for and while loops with break, continue and pass: Simple practice with for loop

This clip is from the chapter "Loops - for and while loops with break, continue and pass" of the series "Complete Python Scripting for...

The impact of antibiotics on human health cannot be overstated. They are a big deal. And thanks to evolution, more and more bacteria are becoming resistant to antibiotics. Is there anything we can do? Yes. Let's talk about it.

👉 Learn how to determine increasing/decreasing intervals. There are many ways in which we can determine whether a function is increasing or decreasing but we will focus on determining increasing/decreasing from the graph of the function....

👉 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...

What is the work-energy theorem?<br/>
Kinetic Energy And The Work - Energy Theorem, Part 3

In this video, the teacher explains how to measure angle openings using a protractor. They demonstrate how to estimate the angle using a sheet of paper and then use a protractor to accurately measure the angle.

This video shows the basic syntaxes of the while loop.
