For example, if we have the differential equation y ′ = 2 x, y ′ = 2 x, then y (3) = 7 y (3) = 7 is an initial value, and when taken together, these equations form an initial-value problem. The differential equation y ″ − 3 y ′ + 2 y = 4 e x y ″ − 3 y ′ + 2 y = 4 e x is second order, so we need two initial values.

EXACT DIFFERENTIAL EQUATIONS 7 An alternate method to solving the problem is ydy = −sin(x)dx, Z y 1 ydy = Z x 0 −sin(x)dx, y 2 2 − 1 2 = cos(x)−cos(0), y2 2 − 1 2 = cos(x)−1, y2 2 = cos(x)− 1 2, y = p 2cos(x)−1, giving us the same result as with the first method. ♦ Example 2.3. Solve y4y 0+y +x2 +1 = 0. ∗ Solution. We have y4 +1 y0 = −x2 −1, y5 5 +y = − x3 3 −x+C, In mathematics, a differential equation is an equation that relates one or more functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two.

The first differential equation has no solution, since non realvalued function y = y (x) can satisfy (y ′) 2 = − x 2 (because squares of real‐valued functions can't be negative). The second differential equation states that the sum of two squares is equal to 0, so both y ′ and y must be identically 0.

In order to convert it into the exact differential equation, multiply by the integrating factor u(x,y)= x, the differential equation becomes, 2 xy dx + x 2 dy = 0. The above resultant equation is exact differential equation because the left side of the equation is a total differential of x 2 y. Solve the differential equation ` (x^2+y^2)dx+2xydy=0`. - YouTube.
