Solve each of the following initial value problems:
,
,
Given and
This is a first order linear differential equation of the form
Here, and
The integrating factor (I.F) of this differential equation is,
We have
∴ I.F = x [∵ elog x = x]
Hence, the solution of the differential equation is,
Recall
⇒ xy = x sin x + c
However, when, we have y = 1
∴ c = 0
By substituting the value of c in the equation for y, we get
∴ y = sin x
Thus, the solution of the given initial value problem is y = sin x
