Hi,
I dont know how to plot this, since there is imaginary unit in the function, please help
x(t) = t^2 + j2πt, 0 ≤ t ≤ 10 , plot the approximate signals using 5 terms of the complex exponential form. This is what is got. Not sure if it right?
clc;
clear all;
close all;
t0 = 0;
T = 10;
w = 2*pi/T
syms t
x = t^2 +(j*2*pi*t)
k = -2:2 %5 terms
a = (1/T)*int(x*exp(-1j*k*w*t),t,t0,t0+T); %%complex exponential

real() imag() abs()
How is k related to the rest of the question? It is not t values as you have negative k but t is nonnegative

k is the 5 terms that the question asked.I know use real, img in this problem but I dont know how to proper use it because I always get error. like how to set it up
