Hello,

I am trying to write a piece of code that allows me to input the numbers of terms in a taylor series and I know that i must use the "k = input('numbers of terms')" comand, when I use: (here is my code)

k = input('total number of terms in the taylor series:');
syms x;
taylor(exp(x), x, 'ExpansionPoint', k)

is k the number of terms? and if not how do i set the number of terms to be expressed?

thank you in advance.

在 MATLAB Online 中打开

taylor(exp(x), x, 'Order', k)

Note that this will expand around x=0 unless you provide an expansion point.

the result is only correct for small values of x

apparently I am completely off base here and don't need to actuallyneed to use the taylor() keyword but need to write a for loop that will actually preform a taylor series for me. sorry that i may have wasted anybodies time with the original question.
