Yes, the first part is correct. The limit of the ratios is 0 so the radius of convergence is infinite. For the second part you need a form for the remainder term in a Taylor series. Weren't you given one? If not look it up and try to estimate it.

Is there a general formula to calculate the max error?

Thanks

Hey dick,

thanks but i think my teachers wants to do it with this formula:

abs(Rn(x)) less than or equal to (M)/(n+1)! abs(x-a)^(n+1)

I dont know what the M equals to tho

M is a bound for the k+1 derivative of f(x) over the interval. Look at the link I sent you. You'll see f^(k+1) instead of M.

Don't delete the problem after you've solved it! Other people with similar problems are supposed to be able to search for previous threads that can help them. Deleting parts of it defeats that.
