I write the limits of integration from 0 to 2*pi when he give me a Full Circle ,, but what I write
instead of 2*pi when he give me half circle as show in figure? :
this statement of matlab when he give me a contour for full circle :
q1=quad(@(t) fun(g(t)).*gprime(t),0,2*pi)
I want instead it by contour for half circle ,, what I write instead( 0,2*pi)?
this problem that I want answer it:
find the integral around half contour
∫(x^3+3)/((x^2+1)(x^2+4))
