This series of videos focusing on calculus covers calculating derivatives, power rule, product and quotient rules, chain rule, implicit differentiation, derivatives of common functions.

You can take the derivatives of f(x) and g(x), but what about f(g(x)) or g(f(x))? The chain rule gives us this ability. Because most complex and hairy functions can be thought of the composition of several simpler ones (ones that you can find derivatives of), you'll be able to take the derivative of almost any function after this tutorial. Just imagine.

Discover what magic we can derive when we take a derivative, which is the slope of the tangent line at any point on a curve.

The topic that is now known as "calculus" was really called "the calculus of differentials" when first devised by Newton (and Leibniz) roughly four hundred years ago. To Newton, differentials were infinitely small "changes" in numbers that previous mathematics didn't know what to do with. Think this has no relevence to you? Well how would you figure out how fast something is going *right* at this moment (you'd have to figure out the very, very small change in distance over an infinitely small change in time)? This tutorial gives a gentle introduction to the world of Newton and Leibniz.

We told you about the derivatives of many functions, but you might want proof that what we told you is actually true. That's what this tutorial tries to do!

Met curator Marla Prather on motion in Alexander Calder’s Mobile, 1941. Alexander Calder was born to a family of sculptors. His grandfather, Alexander Milne Calder (1846-1923), studied with Thomas Eakins and is famous for the elaborate sculptural decorations of Philadelphia's City Hall. Calder himself had studied to be an engineer at the Stevens Institute of Technology before attending the Art Students League in New York. Like many aspiring artists of his generation, Calder then spent time in Paris where he was inspired by Joan Miró's work and absorbed the playfulness of Dada. Indeed, it was the French artist Marcel Duchamp who christened Calder's hanging sculptures "mobiles." For works such as this one, Calder cut sheet metal into various shapes and assembled these elements in a chain-linked system so that the flat metal pieces move in response to currents of air. This particular mobile was included in the 1942 exhibition "Artists for Victory" at the Metropolitan where the sculpture committee awarded it a prize and recommended it be added to the collection. Created by The Metropolitan Museum of Art.

An option, like a call option, can provide leverage because it allows a bet on a stock to be multiplied many times. Learn how call options provide leverage in this video. Created by Sal Khan.

A call payoff diagram is a way of visualizing the value of a call option at expiration based on the value of the underlying stock. Learn how to create and interpret call payoff diagrams in this video. Created by Sal Khan.

Camel, first half of the 12th century, fresco transferred to canvas, from San Baudelio de Berlanga, Spain (Met Cloisters, New York) speakers: Dr. Lauren Kilroy-Ewbank and Dr. Steven Zucker. Created by Smarthistory.

In this video we wire Bit-zee's camera's shutter and power functions to some transistors on the bread board and then we connect the transistors to the Arduino. Created by Karl Wendt.

Now we'll add a lens to our camera and explore the idea of an f-stop.

This video shows you how to reduce the complexity of your Bit-zee while improving the speed of your Bit-zee digital camera. Created by Karl Wendt.
