8.1: Basics of Differential Equations - Mathematics LibreTexts

WebDifferential equations relate a function to its derivative. That means the solution set is one or more functions, not a value or set of values. Lots of phenomena change based on their current value, including population sizes, the balance remaining on a loan, and the temperature of a cooling object. WebQuestion: In Problems 10.53-10.58 you will be given a second-order differential equation. Rewrite it as two coupled first-order equations. Have a computer draw the phase portrait for those two equations, and use that phase portrait to predict the possible time evolution of the system. A good answer would look like "If it starts with x>5 moving ... Web1 Answer Sorted by: 5 Your suspicions are correct, you can convert an $n-th$ order differential equation into an n-dimensional system of first order equations. Let $x_1 = x$, and then we have: $$\begin {align} x_1' &= x' = x_2 \\ x_2' &= x'' = x_3 \\ x_3' &= x''' = -t^2 x_3 - 4 x_1 \end {align}$$ Our new system is: gateway wifi 6
