Question

Solution of differential equation xdy – ydx = 0 represents

  1. a rectangular hyperbola
  2. straight line passing through origin
  3. parabola whose vertex is at origin
  4. circle whose centre is at origin

Hint:

In the question we have to find the solution of the given equation by integrating it then we will observe the equation and determine the characteristic.

The correct answer is: straight line passing through origin


    Given, x dy – y dx = 0
    rightwards double arrow x. d y equals y. d x
rightwards double arrow 1 over y. fraction numerator d y over denominator d x end fraction equals 1 over x. fraction numerator d x over denominator d y end fraction
