A system can be modelled with two coupled differential equations dy1 dt. = - y1+ y2 + u dy2 dt.

### 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. Mainly the study of 3 x 3 ( y ′) 2 + 3 x 2 y y ′ + 5 = 0. To me it looks like quadratic equation with respect to y ′, so I came up to that. y ′ = − 3 x 2 y ± 9 x 4 y 2 − 12 x 3 6 x 3. And from there I got completely stuck.

## Now, on substituting the value of ‘p’ in the equation, we get, ⇒ x 2 + y 2 = 2(x + yy’)x ⇒ 2xyy’ + x 2 = y 2. Hence, 2xyy’ + x 2 = y 2 is the required differential equation. 7. Form the differential equation of the family of parabolas having vertex at origin and axis along positive y-axis. Solution:

Please Subscribe here, thank you!!! https://goo.gl/JQ8NysSolutions to Differential Equations- one parameter family of solutions- two parameter family Now, on substituting the value of ‘p’ in the equation, we get, ⇒ x 2 + y 2 = 2(x + yy’)x ⇒ 2xyy’ + x 2 = y 2. Hence, 2xyy’ + x 2 = y 2 is the required differential equation. 7. Form the differential equation of the family of parabolas having vertex at origin and axis along positive y-axis. Solution: A differential equation usually has infinitely many solutions.
