The differential equation is not exact.
For given question,
we have been given a differential equation
We have to determine given differential equation is exact or not.
Compare it with M dx + N dy = 0
⇒ M = cos(x) and N = y/x
Find the derivative of M with respect to y.
Now, find the derivative of N with respect to x.
Since , given differential equation is not exact.
Therefore, the differential equation is not exact.
