Solve the first order differential equation : (Z 1)(dy/dx) = xy in term of ln |y| = f(x). Z = (x)(x).
Answer Posted / kang chuen tat (malaysia - pen
Rearranging the equation (1/y)(dy) = [ x / (Z 1) ] (dx). Use the additional equation u = Z 1, du = 2x dx, 0.5 du = x dx. Then the equation becomes (1/y)(dy) = (0.5)(1/u) du. Integrating both sides of the equation gives ln |y| = (0.5) ln |Z 1| c where Z = square of x.
