I am unable to use sym(pi) to provide pi as an output.
syms n positive integer
syms x real
Pi = sym(pi);
a0 = 1/Pi * int(x, 0, Pi)
The output runs as
1.5708
This code ran on friend's laptop giving π/2 as output. What could be the reason?

Which MATLAB version do you use ? In R2024b, the output for a0 is pi/2.
syms n positive integer
syms x real
Pi = sym(pi);
a0 = 1/Pi * int(x, 0, Pi)
