Hello!
I have to find the streamlines of the following velocity fields:
1. u=x(1+2t), v=y
2. u=xy, v=0
I have done the following:
1. ##\frac{dx}{u}=\frac{dy}{v} \Rightarrow \frac{dx}{x(1+2t)}=\frac{dy}{y} \Rightarrow \frac{\ln x}{1+2t}=\ln y+c \Rightarrow y=Ce^{\frac{\ln x}{1+2t}} \Rightarrow y=Cx^{\frac{1}{1+2t}}##
Is this correct??
2. ##\frac{dx}{u}=\frac{dy}{v} \Rightarrow \frac{dx}{xy}=\frac{dy}{0}##
How could we continue??
