Question

integrala(3sinx+4cosx)

Answer 1

Stim ca:

$\int\limits {sinx} \, dx =-cos x+C$

$\int\limits {cosx} \, dx =sinx+C$

$\int\limits {f(x)+g(x)} \, dx =\int\limits {f(x)} \, dx +\int\limits {g(x)} \, dx$

Orice constanta iese in fata integralei, asadar vom avea:

$\int\limits {3sinx+4cosx} \, dx =3\int\limits {sinx} \, dx +4\int\limits {cosx} \, dx =-3cosx+4sinx+C$
