# taylor polynomial ln x

You can try graphing your own Taylor polynomials by just typing in a function for f and setting c. Remember not to set nmax > 6 if the function’s higher order derivatives get more complex. You might try f (x) = ln(x), or try a polynomial function, like f (x) = x² – x c?

so as you see i don`t get ln 2 Anood, The Taylor series expression for f(x) at x = a is where f (n) (a) is the n-th derivative of f(x) at x=a if n ≥ 1 and f (0) (a) is f(a). The series you developed for ln(x) at a=2 is correct for n ≥ 1 but what about The first term (n = 0) is f

Find the Maclaurin series expansion for f = sin(x)/x.The default truncation order is 6. Taylor series approximation of this expression does not have a fifth-degree term, so taylor approximates this expression with the fourth-degree polynomial:

We look at various Taylor polynomials: \$\begin{eqnarray} T_1(x)&=&f(a) + f'(a) (x-a)\\ T_2(x)&=&f(a)+f'(a)(x-a)+\frac{f」(a)}{2!}(x-a)^2\\ T_3(x)&=&f(a)+f'(a)(x-a
