i know if every simple closed curve in D can be contracted to a point it is simply connected as in the case of|R^2 Domain or R^3 it is simply connected
but i am not feeling uncomfortable with |R^3 especially with the domains like when x =! 0 and y =! 0 why it is not simply connected?

Evaluate the line integral
Force field is the integral in the form of integrand ( (2x dx+ 2y dy + 2 zdz)/r^2).
the domain of integral is C,
C = C1 + C2. C1 is the line segment from (1; 2; 5) to (2; 3; 3). C2,arc
of the circle with radius 2 and centre (2; 3; 1) in the plane x = 2. The...
