Questions on the analytic and numerical equation solving functions of Mathematica (Solve, Reduce, NSolve, FindRoot, DSolve, RSolve, etc.).

Solving equations and equation systems with Mathematica's toolkit. This includes the analytic solver family: Solve, DSolve, RSolve, LinearSolve, Reduce, FindInstance, etc. that can solve symbolic equations or inequalities in an exact way; and the numerical solver family: NSolve, NDSolve, FindRoot,

Questions should be simple, clear and well stated. Always try to reduce the problem to a bare minimum (even if it is semantically does not make sense) that illustrates the intent of the question. Please double-check that your variables are cleared and parameters and boundary conditions are set (where it is required). Provide code in InputForm and not as row boxes. This site supports $\LaTeX$, so the background information can also be provided in neatly typeset math. Please avoid using $\LaTeX$ in the code itself.

Ideally, the question must also be accompanied by the appropriate math tag such as , or . If simplification is involved consider using the tag .
