WebSep 11, 2024 · 1.9: First Order Linear PDE. We only considered ODE so far, so let us solve a linear first order PDE. Consider the equation. where u ( x, t) is a function of x and t. The initial condition u ( x, 0) = f ( x) is now a function of x rather than just a number. In these problems, it is useful to think of x as position and t as time. WebIn this subsection, we examine some few selected non-linear first order differential equations to demonstrate the strength of the methods under discussion. The quasi-linearization method is used to linearize the equations first. The non-linear first order differential equations are first linearized to enable us to apply the BHMs. iowa high school football forum iowa high school football coaching records
