Let’s get some practice rewriting definite integrals as the limit of a Riemann sum. So let’s say I wanted to take the definite integral from π to 2π of cosine of x dx. What I want to do is write it as the limit as n approaches infinity of a Riemann sum. …

We’re told that the first ionization energy of silver is 7.31 times 10 to the fifth joules per mole. What is the longest wavelength of light that is capable of ionizing an atom of silver in the gas phase? All right. Now, before I even ask you to pause an…

We may sometimes want to alter the normal control flow of our loops to either terminate early or skip an iteration. To do this, we can use the break and continue statements. A break statement tells the computer to immediately terminate the loop. We write …

A force is just a push or a pull, that’s it. But in this video, we’re going to explore the different kinds of pushes and pulls that we will encounter in our daily lives. So let’s start with an example. Imagine you are pulling a chair in your living room u…
