Hello everyone! I am trying to prove that the following inequality is right for all n equal to or larger than 9. I tried using the triangle inequality and then mathematical induction but none of it seems to work. please help!
l e^-1 - (sigma sign from k=0 to n) (1)^-k / k!l
thanks in advance
I know that lerrorl = lxl^(n+1) / (n+1)! for a Pn(x), is that what you mean by alternating series error bound? If that is so, I dont really see how you can use that.
But if you replace f(-1) (which I hadnt seen before) than you get an infinite sum starting from k=n, right? What do you do with the absolute value then?
