WebUpon rearrangement we get [(2m − 3n + 1)y − 2(3m − 2n − 1)x]xnym = 0. This is true if 2m−3n+ 1 = 0 and 3m−2n− 1 = 0, which yields m = n = 1. Therefore, an integrating factor … WebJan 31, 2024 · Observe that the characteristic line of the PDE, 2u t+ 3u x= 0 is 3t 2x= 0. Thus, the solution is the form of u(t;x) = f(3t 2x) for some di erntiable one variable function f. Note that, by the auxiliary condition, u(0;x) = sin(x) ,we have sin(x) = u(0;x) = f( 2x): Let w= 2x, then f(w) = sin w 2 : Therefore, our solution is u(t;x) = f(3t 2x ...
