Vstavitev podatkov v enačbo

573 views

Zanima me kako lahko v enačbo na sliki vstavim podatke.
Vem da se da z funkcijo .subs(podatki), vendar mi ne uspe.
Hvala za pomoč

ali te zanima rezultat ali te zanima samo da pokaže enačbo z vrednostimi?

namesto Eq(a_phi, 'izraz') naredi tako: Eq(a_phi, ('izraz').subs(podatki)) in bi moralo delati

Sem naredil tako, vendar pride rezultat 0, moral pa bi priti 1924 m/s^2.
še kakšna ideja? :)

Da dobiš rezultat lahko uporabiš tudi:
rezultat = a_kro1.evalf(subs=podatki)

ne deluje.. enačbo pusti isto, samo da iz vsake številke naredi float.
