Can any of you link me to a good text on derivatives or try to teach me them?
My parents don't want to teach me since they say I'm only gonna learn them next year, but I can't wait

Ok, derivatives are basically the slope of any point in a function. So for like y=5x, the slope is 5 the entire way across. But what about 5x^2? There as you can see, the slope for every point is different. This is how you do derivatives. For every element, take the exponent of x, multiply it by the coefficient, then subtract one to the exponent. 5x^2 -> 10x(^1). 10x -> 10(x^0), 10 -> 0 (note if you take the derivative of an element with x^0, it goes to 0). Hope that explains it.

Spoiler for IMPORTANT NEWS!: Late last night, Quebec was invaded by a group calling themselves, "Omnimaga". Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do... Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met. In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...
It seems like a derivative is the comparison of the m of a function (as in y=mx+b) of one variable f(x) and another one f(a).
