 IsolateHighestDerivative
 solve the ODE for its highest derivative

 Calling Sequence IsolateHighestDerivative(ODE, y(x))

Parameters

 ODE - an ordinary differential equation y - name; the dependent variable x - name; the independent variable

Description

 • The IsolateHighestDerivative(ODE, y(x)) command solves ODE for the highest derivative of y(x) with respect to x.

Examples

 > $\mathrm{with}\left({\mathrm{Student}}_{\mathrm{ODEs}}\right):$
 > $\mathrm{ode1}≔{t}^{2}\left(z\left(t\right)+1\right)+{z\left(t\right)}^{2}\left(t-1\right)\left(\frac{ⅆ}{ⅆt}z\left(t\right)\right)=0$
 ${\mathrm{ode1}}{≔}{{t}}^{{2}}{}\left({z}{}\left({t}\right){+}{1}\right){+}{{z}{}\left({t}\right)}^{{2}}{}\left({t}{-}{1}\right){}\left(\frac{{ⅆ}}{{ⅆ}{t}}\phantom{\rule[-0.0ex]{0.4em}{0.0ex}}{z}{}\left({t}\right)\right){=}{0}$ (1)
 > $\mathrm{IsolateHighestDerivative}\left(\mathrm{ode1},z\left(t\right)\right)$
 $\frac{{ⅆ}}{{ⅆ}{t}}\phantom{\rule[-0.0ex]{0.4em}{0.0ex}}{z}{}\left({t}\right){=}{-}\frac{{{t}}^{{2}}{}\left({z}{}\left({t}\right){+}{1}\right)}{{{z}{}\left({t}\right)}^{{2}}{}\left({t}{-}{1}\right)}$ (2)

Compatibility

 • The Student[ODEs][IsolateHighestDerivative] command was introduced in Maple 2021.
