is there anybody that should be programming, as opposed to working in a place where they can do some good for the world rather than help make rich people slightly richer?

the general rule for differentiating polynomials comes from the binomial theorem in part binomial theorem is how you get (a+b)^2=aa+ab+ba+bb and (a+b)^3=aaa+aab+aba+baa+bba+bab+abb+bbb if you just start taking binomials to different powers and look for a pattern you will be able to construct the sum notation for the general binomial theorem. limit definition of the derivative, the rate of change of a function at 1 point, is the limit as delta approaches 0 of [f(x + delta) - f(x)] / delta if f(x) = x^n then it's [(x+delta)^n-x^n]/delta the term of (x+delta)^n with x^n and delta^0 is just x^n and it cancels with the minus x^n the term of (x+delta)^n with delta raised to the first power is n*x^(n-1)*delta and that divides with the delta and escapes the limit. all the other terms have at least one additional factor of delta which is going to 0 so they all go to 0 thus you get that the limit as delta approaches 0 of x^n = n*x^(n-1) for integrals it's a little trickier because the definition of the integral is a sum I imagine the typing I just did on the derivative is lovely enough to read so I'll leave that alone

fleshweasel posted:for integrals it's a little trickier because the definition of the integral is a sum Antidifferentiation doesn't have a general closed-form solution, but for polynomials it's sufficient to note that differentiating a polynomial gives us a polynomial, and we can do the same thing backwards to find an antiderivative that differentiates to our original function.

fleshweasel posted:the general rule for differentiating polynomials comes from the binomial theorem in part its a bit simplier if you take the exp() and ln() as given. let n be in R, then d/dx x^n = d/dx exp(ln(x^n)) = exp(ln(x^n))*(d/dx ln(x^n)) = exp(ln(x^n))*(d/dx n*ln(x)) = exp(ln(x^n))*(n/x) = x^n * n/x = n * x^(n-1) but simpler, not easier.
