Some Help with Trig Functions and some basic differential calculus?
Why does the sine and cosine functions repeat every 2pi and tangent every 1pi when graphed?
Also, completely off topic, could someone please explain to me how the 1st derivative of x^2 is 2x? If this is hard to explain...perhaps a link to a easy-to-understand site.
I'm trying to learn calculus on my own and I have a very scattered background. Any help would be appreciated. Thanks

The period of sine and cosine is understood to be 2pi, while the period of tan is understood to be pi, on a basic graph. It is just something you learn. The other one i cant help u with sorry.
