For each of the following vector fields F , decide whether it is conservative or not by computing the appropriate first order partial derivatives. Type in a potential function f (that is, ∇f=F) with f(0,0)=0. If it is not conservative, type N. A. F(x, y)=(4x−5y)i+(−5x+14y)j f(x, y)= -10x^2-35y^2+53xy B. F(x, y)=2yi+3xj f(x, y)= n C. F(x, y)=(2siny)i+(−10y+2xcosy)j f(x, y)= Note: Your answers should be either expressions of x and y (e. g. "3xy + 2y"), or the letter "N"
