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!

Why are youtube teachers so much better than real teachers???

[cxunfsq]

Here’s why YouTube teachers feel so much better then normal teachers.
1. You probably actively looked them up on your free time, unlike school were your basically forced. If your body feels forced to do something it won’t do the task as well.
2. YouTube teachers want you to watch there content a lot, and so whatever they are teaching they put all there effort into just once instead of multiple times unlike normal teachers.
