Is the integration process following P in Cartesian coordinates:
$ z = \cos(x^2+1), \qquad y=1$
Evaluate
$ \int_{(0,1,\cos(1))}^{(1,1,\cos(2))}\hat{F}dl$
Over the integration process P and where
$ \hat{F} = \tan(x)\hat{a}_{y}$
I believe it's something that look like this.... but my cartesian coordinate given are different... I'm not sure about the parametric of my Cartesian coordinate.
