Question Part Points Submissions Used Determine whether or not F is a conservative vector field. If it is, find a function f such that F = âf. (If the vector field is not conservative, enter DNE.) F(x, y) = (yex + sin(y))i + (ex + x cos(y))j
Determine whether or not F is a conservative vector field. If it is, find a function f such that F = âf. If it is not, enter NONE.
a) F(x, y) = (2x â 4y) i + (â4x + 10y â 7) j
b)F(x, y) = ex sin(y) i + ex cos(y) j
c)F(x, y) = (yex + sin(y)) i + (ex + x cos(y)) j
d)F(x, y) = (ln(y) + 6xy3) i + (9x2y2 + x/y) j
