About The Einstein Toolkit is a community-driven software platform of core computational tools to advance and support research in relativistic astrophysics and gravitational physics. The only difference between solving an inequality and solving an equation, is the following: When we multiply or divide by a negative number, the sense must change. (Theorem 3.) Equivalently, when the signs on both sides change, then the sense also must change . Example 1. In carrying out the algorithm to solve the following nonlinear differential equation, Mathematica has to solve a transcendental equation. In doing so, the generically multivariate inverse of a function is encountered, and a message is issued that a solution branch is potentially missed.

May 26, 2012 · Finding X-Intercepts in Mathematica? Ok so I have a graph of x as a function of t, and I want to find the t-intercepts (like the x-intercepts on an x,y graph), or just where x(t) is a certain value. The problem is, the value of x(t) is an Interpolating function. But it’s become clear that for Mathematica itself the name “Mathematica” is in some sense much too narrow—because it gives the idea that all that Mathematica does is math. Mathematica is well suited to solving symbolic calculus problems, including derivatives, integrals, simplifying expressions and collecting similar terms. This sections illustrates the process of solving equations of various forms. It also shows you how to check your answer three different ways: algebraically, graphically, and using the concept of equivalence.The following table is a partial lists of typical equations.
