Dec 03, 16 · Please see below I'm not sure I understand your question I don't know what you mean by "using the derivate number which is f'(a)" If I understand it, I think I need to point out that lim_(xrarra)(x^na^n)/(xa) = f'(a) for f(x) = x^n That is For f(x) = x^n, f'(a) = lim_(xrarra)(f(x) f(a))/(xa) = (x^na^n)/(xa) We also know, by the power rule for derivatives, That for f(x) = x^n,.

I assume you are looking for math\sum_{n\geqslant 1}\frac{x^n}n/math We restrict the value of mathx/math to open regions in math\mathbb R/math or math\mathbb C/math where the series converges One clever way to compute that is by. Which shows that (f(x n)) is a Cauchy sequence (b) Suppose that f(x) = 1=xfor x2(0;1) and x n = 1=nfor n2N Then fis continuous on (0;1) since it is a rational function with nonzero denominator The sequence (x n) is Cauchy since it converges to 0 and every convergent sequence is Cauchy (or give a direct proof) However, y n = f.

Oct 09, 14 · For the function #f(x)=x^n#, n should not equal 0, for reasons which will become clear n should also be an integer or a rational number (ie a fraction) The rule is #f(x) = x^n => f'(x) = nx^(n1)# In other words, we "borrow" the power of x and make it the coefficient of the derivative, and then subtract 1 from the power.
