syms x
f(x) = sin(x)
q = integral(f(x),0,pi)
when I run this I am facing the following error :
"Error using integral (line 82)
First input argument must be a function handle.
Error in integ (line 4)
q = integral(f(x),0,pi) "
Could you please explain why i am unable to put f(x) as a first input argument in the integral after defining the variable x.

integral() is used only for numeric integration.
For symbolic integration, use int() if you want to see the closed form solution (if it exists), or use vpaintegral() for symbolic numeric solutions.
