The electrostatic potential in space is given by the scalar field V(r)=V(x,y,z)=e^y + (3x)^2-4cos(z) Find the potential difference between the points P(1,1,1) and Q(0,0,0). (Hint: Don’t forget to put your calculator into radian mode! And don’t forget units!) I basically can not figure out any other way to do this but to plug in the points then subtract them and that seems too easy and is not at all what we are discussing in class.
