Secara umum persamaan differensial tingkat satu derajat satu ditulis dalam bentuk: M(x,y) dx + N(x,y) dy = 0 = F(x,y) F(x,y,) = 0. Bentuk umum di atas mengakibatkan jenis persamaan differensial tingkat satu derajat satu bervariasi. Untuk lebih memudahkan dalam menentukan primitif atau selesaiaan umum persamaan, maka persamaan differensial ...

dy dx =f x, y y x 0 = y 0 (1) where . f x, y . is a known function and the values in the initial condition are also known numbers. If f. is continuous functions then there is a unique solution to the IVP in some interval surrounding . x = x. 0. So, let’s assume that everything is nice and continuous so that we know that a solution will in ...

dY/dX = X/Y Given a budget constraint, with positive prices for both, the consumer would maximize utility by purchasing only X. On the other hand, if we framed the problem in terms of Y removal, then U = (X2+Y2).5 as we established in the part c, the MRS for such a problem–X/Y exhibits an increasing MRS.

Again, the above equation can be solved by separation of variables: dy = c1 cosh x dx y = c1 sinh x + c2 # Case II: F(y, y', y'') = 0 x does not appear explicitly [Example] y'' + y'3 cos y = 0 [Solution] Again, set z = y' thus, y'' = = = y' = z
