Ho provato a risolvere la seguente equazione differenziale:

u'+utant=cost

Ho trovato come soluzione u(t)= t cost + C IcostI. Dove C è la costante. Ora mi chiedo, essendo il valore assoluto del coseno a moltiplicare la costante, posso tranquillamente sbattere via il valore assoluto e dire che la soluzione dell'equazione è u(t)= t cost + C cost ?
