Question

The solution of the differential equation x dx + y dy = 0 ​

Answer 1

Answer:

Step-by-step explanation:

Given, xdy−ydx=0

⇒  

y

dy

​  

−  

x

dx

​  

=0

On integrating, we get

logy−logx=logc

⇒log  

x

y

​  

=logc

⇒  

x

y

​  

=c

⇒y=cx, which is a straight line passing through the origin.
