Questions & Step-by-Step Solutions

What is the particular solution of dy/dx = 4x with the initial condition y(0) = 1?
  • Step 1: Start with the differential equation dy/dx = 4x.
  • Step 2: Integrate both sides with respect to x. This means we find the antiderivative of 4x.
  • Step 3: The integral of 4x is 2x^2 + C, where C is a constant.
  • Step 4: Now we have the general solution: y = 2x^2 + C.
  • Step 5: Use the initial condition y(0) = 1 to find the value of C.
  • Step 6: Substitute x = 0 into the equation: y(0) = 2(0)^2 + C = 1.
  • Step 7: This simplifies to C = 1.
  • Step 8: Substitute C back into the general solution to get the particular solution: y = 2x^2 + 1.
