## Homework Statement

Okay, so I need some help with this Matlab program. I never learned Matlab, so I'm trying to do it as best as I can. The question is: Calculate the 2nd and 3rd degree Taylor polynomials for the function f(x)=ln(1+x) about the point a=0 Plot these polynomials and the function on the interval -1<x<3

## Homework Equations

N/A

## The Attempt at a Solution

This is what I have so far. I thought it was right, but Matlab said "Not enough input arguments." What does that mean, and I how do I fix it?

>> figure(1);clf;

x=[-1:.01:3];

y=log*(1+x);

P2= x-(x^2/2)!;

P3= x-(x^2/2)+(x^3/3)!;

figure(1);clf;

plot(x,y,x,P2,'--',x,P3,'-.')

legend('log*(1+x)','P_2','P_3')

xlabel('x')

figure(2);clf

plot(x,abs(y-P2),x,abs(y-P3),'--')

legend('log*(1+x)-P_2|','log*(1+x)-P_3|')

xlabel('x')

Thanks in advance!:)
