Determine if the following statements are true or false. (a) if ∫c vector f · d vector r = 0 for one closed path c, then vector f is path-independent. true false (b) if the total change of a function f along a curve c is zero, then c must be a contour of f. true false (c) line integralc vector f · d vector r = vector f(q) - vector f(p) when p and q are the endpoints of c. true false (d) if vector f is continuous and vector f = gradf, then vector f is path-independent. true false (e) if f(x) and g(y) are continuous one-variable functions, then the vector field vector f = f(x)vector i + g(y)vector j is path-independent. true false (f) the vector field vector f( vector r ) = vector r in 3-space is path-independent.

The vpython command norm returns the unit vector of a vector. remember that a unit vector has a length of one and points in the direction of the original vector. for exampe, if l = vector(0,3,0) then norm(l) = < 0,1,0> and, if l = vector(0,3,0) then norm(-l) = < 0,-1,0> additionally, if l = vector(0,3,0) then norm(5l) = < 0,1,0> and, for example, if m = vector(1,1,0) then norm(m) = < 0.707,0.707,0> . another example, if n = vector(2,3,0) then norm(m) = < 0.5547,0.83205,0> an for another example, if p = vector(1,2,3) then norm(p) = < 0.267261,0.534522,0.801784> if q = vector(3,4,0) then norm(q) =
