How do you complete problem number 4?
brilliants [131]
(I'm going to translate y' to dy/dx as it makes it easier to read for me, you could change it back if you wanted.)
x \frac{dy}{dx} -y=0
\frac{dy}{dx} = \frac{y}{x}
\int \frac{1}{y} dy= \int \frac{1}{x} dx (separate the variables)
\ln y=\ln x +c
\ln y = \ln kx (by letting c = ln k and using log laws)
y=kx (raise everything to power e)
3=k\times1 \implies k=3    (applying boundary conditions)
Particular solution: y=3x
