Dear Javid, here is the code for your problem:
A = input('Enter value of A:');
B = input('Enter value of B:');
D = input('Enter value of D:');
alpha = input('Enter value of alpha:');
beta = input('Enter value of beta:');
gamma = input('Enter value of gamma:');
sigma = input('Enter value of sigma:');
n = input('Enter value of n:');
a0 = A * alpha + B * (gamma - beta) + D * (1 - sigma);
val = 1:n;
a = (-1 / (pi * val)) * (A * sin(2 * pi * val * alpha) - B * (sin(2 * pi * val * gamma) - sin(2 * pi * val * beta)) - D * (sin(2 * pi * val) - sin(2 * pi * val * sigma)));
b = (1 / (pi * val)) * (A * (cos(2 * pi * val * alpha) - 1) + B * (cos(2 * pi * val * gamma) - cos(2 * pi * val * beta)) + D * (cos(2 * pi * val) - cos(2 * pi * val * sigma)));
I hope it is what you need. Good luck!
