Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

The Spanish Flu, as the virus is now known, made its way around the world mindless of human politics, borders and morality, infecting soldiers and civilians, rich and poor alike. Its spread was so wide-reaching that the only continent it left untouched was Antarctica.
By the time the virus had run its course, approximately 500 million people, roughly one third of the world’s population, had fallen ill.
Conservative estimates place the death toll at 20 million people, but it is now widely accepted that the much more likely figure lies somewhere between 50 - 100 million.

In the Russo-Ukrainian War, thousands of BTRs have been deployed and destroyed. Having already been often sighted within conflicts even as far as Afghanistan, Cuba, Egypt, and Iran during the Cold War, here we describe their various technical designs, how they have been continuously tinkered with, and their intended purposes. Beginning with the BTR-60 not long after World War II, and exploring their unusual amphibious capabilities, we conclude with the latest formidable BTR-82A and their impacts on the battle-zones.

At five am on the 3rd of October 1935 Italian forces crossed into Abyssinia, modern day Ethiopia, signalling the start of the Second Italian-Abyssinian War.
The war’s outcome would not only change the face of Africa but the political rifts it caused between the fascist nations and the democratic nations would contribute to the beginning of the most devastating conflict the human race has ever known, the Second World War.

This calculus video tutorial provides a basic introduction into solving bernoulli's equation as it relates to differential equations. You need to write the differential equation into the standard form of Bernoulli's equation and identify P(x), Q(x), and n. If n = 0, you have a linear differential equation. If n = 1, then you have a differential equation that can be solved by separation of variables. Next, you need to identify the integrating factor I(x) and then you find the general solution to Bernoulli's differential equation. This video contains plenty of examples and practice problems.

This calculus video tutorial explains how to find the local maximum and minimum values of a function. In order to determine the relative extrema, you need to find the first derivative, set it equal to zero, and solve for x which represents the critical numbers of the function. You need to put these numbers on a number line and create a sign chart. According to the first derivative test, if the sign changes from - to +, it's a relative maximum. If it changes from + to -, it's a relative minimum. This video contains plenty of examples and practice problems for you to work on.
