      The symbols dy and dx are called differentials of y and x. Another way of driving the differentials is to treat the derivative ratio as two separate components, that is, treat dy/dx as two separate entities. Taking the identity, dy/dx = dy/dx = f’(x) and dividing each side by dx, we obtain. Find the differential of the function dy = 3x2 + 7x ...

      = tanh x dx = dx. or ln|z| = ln|cosh x| + c' z = c1 cosh x. or y' = c1 cosh x. 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
