Extracted text: Determine whether the equation is exact. If it is, then solve it. 1 бу cos (хy) + dx + [6x сos (ху) — Зу 9. |dy = 0 1-X Select the correct choice below and, if necessary, fill in the answer box to complete your choice. = C, where C is an arbitrary constant. The equation is exact and an implicit solution in the form F(x,y) = C is O A. (Type an expression using x and y as the variables.) O B. The equation is not exact.
