Questions & Step-by-Step Solutions

Solve the equation dy/dx = y^2 - x.
  • Step 1: Identify the equation dy/dx = y^2 - x. This is a differential equation.
  • Step 2: Recognize that this is a separable equation, meaning we can separate the variables y and x.
  • Step 3: Rearrange the equation to isolate y on one side and x on the other. We can write it as dy/(y^2 - x) = dx.
  • Step 4: Integrate both sides. The left side will involve integrating with respect to y, and the right side with respect to x.
  • Step 5: After integrating, you will get an expression involving y and x. This will lead to a form that can be solved for y.
  • Step 6: Solve for y to get the final solution in the form y = 1/(C - x), where C is a constant.
