Q

Como calcular Puntos Criticos

A

Maximo f’(a) = 0, f’‘(a) <0
Minimo f’(a)=0, f”(a) >0
Inflexion f’(a)=0, f”(a) = 0
Primera derivada = 0, Los valores de x se sustituyen en la segunda derivada a ver si es max o min

Q

Transformada de Laplace

A

L(y”) = s^2Y(s)-sy(0)-y’(0)
L(y’)=sY(s)-y(0)
L(y)= Y(s)
Se despeha para Y(s) y luego se aplica el L-1
