WebApr 11, 2024 · Over the last couple of months, we have discussed partial differential equations (PDEs) in some depth, which I hope has been interesting and at least somewhat enjoyable. Today, we will explore two of the most powerful and commonly used methods of solving PDEs: separation of variables and the method of characteristics. WebThe solution is perfect, but why did you keep dy in the last (green) row. Listen, you have integrated the whole equation, on rhs you got x^2/2+C and on the lhs you get -e^ (-y). Then you are given the initial condition aka Cauchy problem. As function passes the origin simply substitute (0;0) inside your function to obtain the value of constant. rdk serviceshttp://people.uncw.edu/hermanr/pde1/pdebook/green.pdf rdkb building inspector
