Example 1: – Form the differential equation corresponding to y = e^x by eliminating m.

Solution:

Given equation, y = e^mx

On differentiating the above equation for x we get

But y = e^mx

Now we have, y = e^mx

Applying log on both sides, we get,

log y = mx

which gives

So, putting this value of m in  dy/dx  =my   we get

Hence,

is the differential equation corresponding to y = e^mx.

Example 2: – Find out the particular solution of the differential equation ln dy/dx  = 4y + ln x, given that for x = 0, y = 0.

Solution: ln dy/dx  = 4y + ln x

dy/dx  = e^4y × e^{ln x}

dy/dx  = e^4y × (x) 

1/e^4ydy = x dx

e^-4ydy = x dx 

Integrating both sides with respect to y and x respectively we get,

 =  + c

y(0) = 0                    [Given]
