MCQ
A homogeneous dofferential equation of the from $\frac{\text{dx}}{\text{dy}}=\text{h}(\frac{\text{x}}{\text{y}})$ can be solved by making the substitution:
  • A
    y = vx
  • B
    v = yx
  • ✓
    x = vy
  • D
    x = v
✓

Answer

Correct option: C.
x = vy
A homogeneous differential of the from $\frac{\text{dx}}{\text{dy}}=\text{h}(\frac{\text{x}}{\text{y}})$ can be solved by sunstituting x = vy.
