​

Answer 1

Answer:

Condition for an exact differential - Hmolpedia. meaning that the partial derivative of the function P with respect to y at constant x equals the partial derivative of the function P with respect to x at constant y.

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Definition:The differential equation M(x,y) dx + N(x,y) dy = 0 is said to be an exact differential equation if there exits a function u of x and y such that M dx + N dy = du. We claim: The differential equation M. dx + N. dy = 0 is an exact differential equation.
