UserFunction SymmetricPower


The first argument $u$ has the type $LODE$ which abbreviates LinearOrdinarDifferentialEquation.

The meaning of its parameters is as follows.

$C:$ Type of coefficients.

$y:$ Dependent variable.

$x:$ Independent variable.

Specification. The $n$-th symmetric power of the first argument is returned.

Examples. The input for the examples is given in Reduce algebraic mode syntax. The output is returned in a separate window.



The Differential Equation:

$y''-\frac{x-\frac{3}{16}}{x^{2}}{y} = 0$
The $2^{nd}$ symmetric power:
$y'''-\frac{16x-3}{4x^{2}}y'+\frac{2x-\frac{3}{4}}{x^{3}}y= 0$
