Which of the following transformation reduce the differential equation log z = (log z) 2 into the form + P (x) u = Q (x)?

u = log z

u = e z

u = (log z) − − 1

u = (log z) 2

Text Solution

Verified by Experts

The correct answer is:

Dividing the given equation by z (log z) 2 , we get

. … (1)

Writing = u, we have = − − (log z) − − 2 .

So (1) can be written as

− − ⇒ ⇒

which is the required form with P (x) = and Q (x) =
