Series | Telescoping Series Example

This video is a lecture presentation on how to calculate the density of a substance. The presenter explains how density is the property of a substance that defines how massive that substance is per unit volume. The video shows examples...

In this lesson, students will learn how to solve quadratic problems when the coefficient "a" is greater than one. They will explore the factored form of quadratic functions to find zeros and lines of symmetry.

The bar is purely rotating about the pin support. However, we can view this phenomenon as simultaneously rotating about the center of mass while the center of mass is moving in a circular path. This means we have to include both the...

This video is a lecture on efficiency where the speaker explains how to calculate the efficiency of a device and identify the energy transfers that take place. The video starts with an introduction to Sankey diagrams that detail all the...

In this video, we will do a second example calculation using the ideal gas equation of state, PV=nRT. [Solving for pressure, P]

Although the Greeks initially thought all numeric qualities could be represented by the ratio of two integers, i.e. rational numbers, we now know that not all numbers are rational. How do we know this?

A description of basic circuit analysis with Arduino.

In this lesson, students learn how to solve exponential equations when the base is not 10 or E by using logarithms. They are taught the property that the logarithm of a base to the X power is equal to X times the logarithm of the base....

This video is a lecture presentation on the principle of conservation of momentum. It explains the concept of conservation of momentum and applies it to various situations, including collisions and cutting a piece of string between two...

Understand how to add integers using color counters. By combining the counters and canceling out zero pairs, students can easily visualize and solve addition problems involving integers. The teacher emphasizes the importance of neatness...

The bar is purely rotating about the pin support, so if we view the bar as rotating around the pin, then the translational component of the kinetic energy will be 0 (because the pin is not moving). The change in gravitational potential...

👉 Learn how to evaluate the limit of a function using the difference quotient formula. The difference quotient is a measure of the average rate of change of the function over an interval, h. The limit of the difference quotient gives the...

The laws of indices make complex sums involving powers much easier to handle.



There are 6 laws we need to know and understand: how to multiply and divide with indices, raising a power to a power, what a power of 0...

Protein Purification Table Calculations: Formulas, No Numbers

In this video, you will learn how to complete the square using algebra. We go through the steps to determine the values of A, B, and C in a quadratic expression and how to use them to complete the square. Through these examples, you will...

This video is an example problem that walks through finding the average speed for the last 2 laps of the 4 lap qualifier for the Indianapolis 500 assuming an average speed for the first 2 laps. It is actually more difficult than it...

This is a lecture video on the turns ratio equation for transformers. The video explains how the potential difference across the primary and secondary coil of a transformer depends on the number of turns of wire in each of the coils. The...

Social media companies face a tough choice in censoring their users. Steven Pinker joins Steven Edginton to discuss rationality, big tech companies and conspiracy theories in the latest Off Script podcast. Watch the full episode above or...

This video is a lecture presentation on orbits. It discusses how an object remains in orbit and what affects the orbital speed of an object. The presenter explains the role gravity plays in keeping celestial bodies in orbit and gives...

👉 Learn how to solve two step linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. To solve for a variable in a two step linear equation, we first isolate the variable by using inverse...
