You are approximating a definite integral with cumtrapz it won't give you the same result as the integrated equation unless you add a constant and plot with the given x coordinates: import numpy as np import matplotlib.pyplot as plt import scipy.integrate as it x = np.arange(-10,10, 0.01) # start,stop,step f = x**2 f_int=it.cumtrapz(f,x, initial=0) plt....

So why don't you very literally do what is being asked. The difference between two curves is the surface area between the two curves. This is 1 number, which you can then plot as a function of the number of terms in the Taylor expansion. There is however a small snag, the area will depend on the range of x's you consider. So there are two options, either you ...

Sounds like you want to omit the use of a MATLAB toolkit/Octave package. Of course you can build the bode diagram from scratch: % transfert function as anonymous function h = @(s)(1)./(2*s.^2+3*s+4); % frequency vector w = 2*pi*logspace(-2,2,1000); % magnitude & phase estimation mag = abs(h(1j*w)); magDB = 20*log10(mag); phaseDeg = rad2deg(angle(h(1j*w))...
