Determine whether the equation is exact. If it is, then solve it. (- sin x cos y + 10x)dx- (cos x sin y + 8y)dy = 0 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The equation is exact and an implicit solution in the form F(x,y) = C is = C, where C is an arbitrary constant. (Type an expression using x and y as the variables.) OB. The equation is not exact.
