Solution for xdy-ydx=sqrt(x^2+y^2) equation:


Simplifying
xdy + -1ydx = sqrt(x2 + y2)

Combine like terms: dxy + -1dxy = 0
0 = sqrt(x2 + y2)
0 = (x2 * qrst + y2 * qrst)
0 = (qrstx2 + qrsty2)

Solving
0 = qrstx2 + qrsty2

Solving for variable 'q'.

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

Add '-1qrstx2' to each side of the equation.
0 + -1qrstx2 = qrstx2 + -1qrstx2 + qrsty2
Remove the zero:
-1qrstx2 = qrstx2 + -1qrstx2 + qrsty2

Combine like terms: qrstx2 + -1qrstx2 = 0
-1qrstx2 = 0 + qrsty2
-1qrstx2 = qrsty2

Add '-1qrsty2' to each side of the equation.
-1qrstx2 + -1qrsty2 = qrsty2 + -1qrsty2

Combine like terms: qrsty2 + -1qrsty2 = 0
-1qrstx2 + -1qrsty2 = 0

Factor out the Greatest Common Factor (GCF), '-1qrst'.
-1qrst(x2 + y2) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'qrst' equal to zero and attempt to solve: Simplifying qrst = 0 Solving qrst = 0 Move all terms containing q to the left, all other terms to the right. Simplifying qrst = 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 '(x2 + y2)' equal to zero and attempt to solve: Simplifying x2 + y2 = 0 Solving x2 + y2 = 0 Move all terms containing q to the left, all other terms to the right. Add '-1x2' to each side of the equation. x2 + -1x2 + y2 = 0 + -1x2 Combine like terms: x2 + -1x2 = 0 0 + y2 = 0 + -1x2 y2 = 0 + -1x2 Remove the zero: y2 = -1x2 Add '-1y2' to each side of the equation. y2 + -1y2 = -1x2 + -1y2 Combine like terms: y2 + -1y2 = 0 0 = -1x2 + -1y2 Simplifying 0 = -1x2 + -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.
