Power series

IMPORTANT Some of these functions require the Symbolic Math Toolbox to work. Make sure it is installed before trying to use them.

Power series operations

• taylor(f,var,a,”Order”,n) computes the Taylor expansion series of a symbolic expression f with respect to a variable var, around the point a up to the nth order. To do Maclaurin set a to 0. Full documentation

    syms x;
    f = cos(x);
    taylor(f,x,0,"Order",5)
  

Plotting

• fplot(f(x),Range) similar to plot() but instead it takes a symbolic function and a range as [xmin xmax] to plot the function through. If the Range argument is omited the range is [-5 to 5]. Full Documentation

    fplot(f)
    hold on
    fplot(taylor(f,x,0,"Order",5))
