Evaluate the line integral of f(x,y) = x+2y along C, where C is the path counterclockwise around the upper half of the unit circle
Attempt:
parametric r(t)= cos(t)i + sin(t)j 0<t<pi ds=root(1)dt
integrate from 0 to pi the function cost + 2sint, and i get -2.
correct answer is 4. i think im writing the parametric wrong or something. help?
