For each of the differential equations in question, find the general solution:

Separating variables,

Integrating both sides,

Now to integrate we have to multiply it by 1

because,

∵ { - i)

So,

According to i)

Let u be and v be 1

We can take the values of u and v from the formula (I.L.A.T.E)

So,

Or

putting the value of t,
