Differential equation:
Equation y-2*y'+y''=e^x/x
Equation y'=-2+y^2/x^2
Equation y"-2y'+2y=0
Equation x^2dy+(y-1)dx=0
Identical expressions
(sqrt(four -y^ two))dx-y(sqrt(nine -x^ two))dy= zero
( square root of (4 minus y squared ))dx minus y( square root of (9 minus x squared ))dy equally 0
( square root of (four minus y to the power of two))dx minus y( square root of (nine minus x to the power of two))dy equally zero
(√(4-y^2))dx-y(√(9-x^2))dy=0
