The video discusses the differences between the classical long-run aggregate supply curve (LRAS) and the Keynesian aggregate supply curve, with a focus on their shapes and shifts based on changes in factors of production.

With recent high-profile security decryption cases, encryption is more important than ever. Much of your browser usage and your smartphone data is encrypted. But what does that process actually entail? And when computers get smarter and...

In this video, the teacher explains the concept of positive and negative numbers by comparing their distance and direction from zero. The teacher uses number lines and real-life examples, such as money and temperature, to illustrate how...

Learn all about parabolas in conic sections. We will discover the basic definitions such as the vertex, focus, directrix, and axis of symmetry. We will also take a look a basic processes such as graphing, writing the equation and...

This video explains the concept of terminal velocity using velocity time graphs. The video starts with a brief recap of how the force acting on a free falling object changes over time. The video then explains how air resistance affects a...

Learning to sight read advanced piano music involves improving your skills in both horizontal and vertical sight reading. Some keyboard players tend to read individual lines from left to right on the score. This is useful for absorbing...

Now that we have dropped the ball into the bucket, we can determine the final velocity of the ball right before it strikes the bucket. Don't forget that velocity is a vector and has both magnitude and direction. Yep, component vector...

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a...

Hi, everyone, I’m Audrey from Janus Academy, an established language school based in Singapore. We focus on teaching Chinese and Japanese, specialize in Chinese phonetics. Hope you find our videos interesting and educational. In this...

This nugget shows how shapes can be made to look the same by reflecting them through mirrors or rotating them through various turns.

While a barcode only holds information in the horizontal direction, a QR code does hold information in both horizontal and vertical directions. Due to this, a QR code holds hundreds of times more information than a barcode.

This video shows how to find the magnitudes of reaction forces of pins. A general approach to this question is to 1) draw a FBD 2) use Mtotal = 0 and Ftotal =0 3) solve the algebra. A few things to note are: Pin supports apply external...

Here I prove the result that the sum of moments about the center of mass = I_G alpha and the sum of moments about a fixed point = I_o alpha.

Graphing Polar points as they compare to rectangular points

👉 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...

👉 We will explore how to evaluate the limit at infinity. When evaluating the limit at infinity or negative infinity we are interested to know where is the graph going right and left. This is also commonly explored as end behavior of the...

👉 Learn how to determine the extrema, the intervals of increasing/decreasing, and the concavity of a function from its graph. The extrema of a function are the points where the graph changes from increasing to decreasing or vice versa. A...

Learn how to graph horizontal ellipse which equation is in general form. A horizontal ellipse is an ellipse which major axis is horizontal. When the equation of an ellipse is written in the general form, we first rewrite it in standard...

👉 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...

Given certain parameters, how would you solve this other problem? Projectile Motion, Part 5

Hey there! Looking for fun, awesome piano lessons for kids ages 6-10? Check out this video!

👉 Learn how to reflect points and a figure over a line of symmetry. Sometimes the line of symmetry will be a random line or it can be represented by the x or y-axis. Either way when reflecting a point and or figure over the line of...

Calculus based review of Simple Harmonic Motion (SHM). SHM is defined. A horizontal mass-spring system is analyzed and proven to be in SHM and it’s period is derived. The difference between frequency and angular frequency is shown. The...

What is the horizontal distance the cannon ball moves? There are a few ways to approach this problem. I personally strongly recommend applying the fundamental formulas directly rather than get used to the projectile motion formulas -...
