# Solve , y(1) = - 1.

Given, A differential equation To find: Find the solution of the differential equation , for y(1) = - 1

Explanation: We have given a differential equation We can write it as , Now, integrating both sides,   Here, we know, and For y, and So, …(i)

Now, y(1) = - 1 , then

Put x = 1 and y = - 1 in equation (i) - 1 - 2 log 1 = 1 + 2 log 1 + C

- 1 = 1 + C

C = - 2

On putting C = - 2 in equation (i), we get Since, mlog n = log nm

y - x + 2 = log (y + 2)2 + log x2

Since, log m + log n = log mn

y - x + 2 = log (x2(y + 2)2)

Hence, The solution of the given differential equation is

y - x + 2 = log(x2(y + 2)2)
