Hello I am working on high order polynomials and I have two questions:1. Is there a method other than the one based on the "synthetic division with testing the signs" for identifying the lower and upper limits of the real roots? 2. Is there a way for identifying the smallest interval on the...

What is the general method for solving a differential equation of the form \begin{equation} \frac{\partial^{2}z}{\partial x^{2}}+\frac{\partial^{2}z}{\partial y\partial x}=C\end{equation} where C is a constant.

I have the following 2D Poisson equation (which can also be transformed to Laplace) defined on a triangular region (refer to plot): \begin{equation} \frac{\partial^{2}u}{\partial x^{2}}+\frac{\partial^{2}u}{\partial y^{2}}=C\end{equation} with the following three boundary conditions...
