Solution:

  • Order: Highest derivative is d³x/dt³ ⇒ 3
  • Degree: Power of highest order derivative is 1 ⇒ 1
  • Nature: Non-linear due to (dx/dt)²

Question: Form the differential equation representing the family of curves:

y² = (x - c)³

Solution:

  1. Differentiate both sides: 2y dy/dx = 3(x - c)²
  2. From the original equation: x - c = y2/3
  3. Substitute back to eliminate c and form the differential equation.

Question: Solve the differential equation: dy/dx + y tan x = sin x

Solution:

  • Identify P(x) = tan x, Q(x) = sin x
  • Integrating Factor (IF) = e∫tan x dx = 1/cos x
  • Multiply entire equation by IF and solve using the method of integrating factor.

Question: A balloon's surface area S is S = 4πr². If dS/dt ∝ r, find the relation between r and t.

Solution:

  • Given: dS/dt = k r
  • But S = 4πr² ⇒ dS/dt = 8πr (dr/dt)
  • Equating: 8πr dr/dt = kr ⇒ dr/dt = k / (8π)
  • Integrate: r = (k/8π)t + C
