1.) Evaluate the line integral over y=x^2 (0 F=(2x+2y)i + (x^2 -y)j
my actual answer came out to be 5/3... but why does our instructor say that the answer should come out to be 1. Did he do something wrong???

b.) Evaluate the line integral F =yi + x^2j over y=(1/2)x^2 (0 Once again I ended up with -6 when performed myself.
