( x − a ) n = f ( a ) + f ′ ( a ) 1 ! ( x − a ) + f ′ ′ ( a ) 2 ! ( x − a ) 2 + f ′ ′ ′ ( a ) 3 ! ( x − a ) 3 + ⋯ f(x) = \sum _{n=0}^{\infty}{\frac{f^{(n)}(a)}{n!}}(x-a)^{n} = f(a) + {\frac {f’(a)}{1!}}(x - a) + {\frac {f’’(a)}{2!}}(x - a)^{2} + {\frac {f’’’(a)}{3!}}(x - a)^{3} + \cdots f ( x ) = n = 0 ∑ ∞ n ! f ( n ) ( a ) ( x − a ) n = f ( a ) + 1 ! f ′ ( a ) ( x − a ) + 2 ! f ′ ′ ( a ) ( x − a |
