Translating a graph of sine or cosine horizontally can be fun, but you need to understand how it works. Follow along with this tutorial to learn how to horizontally shift the sine and cosine graphs!
Subtracting a negative from a positive? Just remember: subtracting a negative is the same as adding a positive. See how it works in this tutorial!
Ever slide something across a table? If so, then you have performed a translation! In this tutorial, learn the definition of translation and see some really neat examples. Take a look!
You can use the unit circle to help you graph the cosine function! In this tutorial, you'll learn how to do exactly that!
Periodic functions have some special qualities! In this tutorial, you'll be introduced to these functions and learn what a graph must have to be called a periodic function.
