y^{'''}-y^{''}+y^'-y=0

Lösung

y^{^{'''}} - y^{^{''}} + y^{^{'}} - y = 0

y = c_{1} e^{t} + c_{2} cos (t) + c_{3} sin (t)

Schritte zur Lösung

y^{'''} (t) - y^{''} (t) + y^{'} (t) - y = 0

Solve linear ODE:

y = c_{1} e^{t} + c_{2} cos (t) + c_{3} sin (t)

y = c_{1} e^{t} + c_{2} cos (t) + c_{3} sin (t)
