Solution for xdy-ydx=(1+y^2)dy equation:


Simplifying
xdy + -1ydx = (1 + y2) * dy

Combine like terms: dxy + -1dxy = 0
0 = (1 + y2) * dy

Reorder the terms for easier multiplication:
0 = dy(1 + y2)
0 = (1 * dy + y2 * dy)
0 = (1dy + dy3)

Solving
0 = 1dy + dy3

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-1dy' to each side of the equation.
0 + -1dy = 1dy + -1dy + dy3
Remove the zero:
-1dy = 1dy + -1dy + dy3

Combine like terms: 1dy + -1dy = 0
-1dy = 0 + dy3
-1dy = dy3

Add '-1dy3' to each side of the equation.
-1dy + -1dy3 = dy3 + -1dy3

Combine like terms: dy3 + -1dy3 = 0
-1dy + -1dy3 = 0

Factor out the Greatest Common Factor (GCF), '-1dy'.
-1dy(1 + y2) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'dy' equal to zero and attempt to solve: Simplifying dy = 0 Solving dy = 0 Move all terms containing d to the left, all other terms to the right. Simplifying dy = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + y2)' equal to zero and attempt to solve: Simplifying 1 + y2 = 0 Solving 1 + y2 = 0 Move all terms containing d to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + y2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + y2 = 0 + -1 y2 = 0 + -1 Combine like terms: 0 + -1 = -1 y2 = -1 Add '-1y2' to each side of the equation. y2 + -1y2 = -1 + -1y2 Combine like terms: y2 + -1y2 = 0 0 = -1 + -1y2 Simplifying 0 = -1 + -1y2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
