differential equations
the directions are to determine whether or not the equation is exact if so then solve it. the question is (xy^3+ysinx)dx = (3xy^2+2ycosx)dy i solve and i got that it is exact because My is 3y^2+2ysinx and Nx is 3y^2+2ysinx

implicit differentation 1.y^3=4(x^2+y^2) 2.y^23x+2y=0 help please You consider y to be a function of x, but you don't explicitely solve for it. Then you formally differentiate w.r.t. x using the chain rule: y^3(x) = 4(x^2+y^2(x))
