The average variable cost curve is typically U-shaped or upward-sloping, as it is below the average total cost curve. The difference in total cost between two levels of output is divided by the ...

We can calculate the gradient of a tangent to a curve by differentiating. In order to find the equation of a tangent, we: Differentiate the equation of the curve Substitute the \(x\) value into the ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
