This can also be derived from a Power Series whose interval of convergence is (c-R, c+R) where R is a positive real number.

The Taylor series for "f" about "c" can be written as follows

f(x) = f(c) + f'(c)(x-c) +{ f''(c)(x-c)2}/2! + {f'''(c)(x-c)3}/3! + ... + { fn(c)(x-c)n}/n! + ...

When c = 0, the Taylor Series is equivalent to Maclaurin Series.


Example:


1. Use Taylor Series to expand ex around 1.

Solution: f(x) = ex and f(1) =e

f'(x) = ex and f'(1)=e

f''(x) = ex and f''(1) =e and so on.

Therefore, f(x) = e + e(x-1) + {e(x-1)2}/2! + {e(x-1)3}/3! + ...
