Question 68Asked in BPSC TRE 1.0 (2023) Mathematics Class 11-12

The general solution of the differential equation dy/dx = e^(x − y) + x²e^(−y) isअवकल समीकरण dy/dx = e^(x − y) + x²e^(−y) का व्यापक हल है

अवकल समीकरण dy/dx = e^(x − y) + x²e^(−y) का व्यापक हल है
  1. Aeʸ = eˣ + x³/3 + ceʸ = eˣ + x³/3 + c
  2. Beʸ = eˣ + x³/3eʸ = eˣ + x³/3
  3. Cy = x + e^(x³/3) + cy = x + e^(x³/3) + c
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं

Correct answer: (A) eʸ = eˣ + x³/3 + ceʸ = eˣ + x³/3 + c

Explanation

Multiply by eʸ: eʸ dy = (eˣ + x²) dx. Integrating gives eʸ = eˣ + x³/3 + c.eʸ से गुणा करने पर eʸ dy = (eˣ + x²) dx। समाकलन करने पर eʸ = eˣ + x³/3 + c।
