Taylor Series Examples

What this calculator is for

A Taylor series approximates a function near a center using derivatives at that center. Around zero, it is called a Maclaurin series. Use it to check your setup, compare steps with your own work, and review the meaning of the final expression before copying it into homework.

How Taylor series are formed

  1. Choose the center \(a\).
  2. Compute derivatives at \(a\).
  3. Use \(\sum f^{(n)}(a)(x-a)^n/n!\).

Manual example

  1. Problem: Taylor series for \(e^x\) at \(0\).
  2. Every derivative of \(e^x\) is \(e^x\), and \(e^0=1\).
  3. So \(e^x=1+x+x^2/2!+x^3/3!+\cdots\).

Common mistakes to avoid

  • Using \(x^n\) when the center requires \((x-a)^n\).
  • Forgetting the factorial in the denominator.
  • Assuming a Taylor polynomial is exact everywhere.

When to double-check the result

Taylor approximations are local. The farther you move from the center, the more important convergence and remainder estimates become.
