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

(1 + x2)dy + 2xy dx = cot x dx (x ≠ 0)

It is given that


This is equation in the form of (where, p = and Q = )


Now, I.F. =


Thus, the solution of the given differential equation is given by the relation:


y(I.F.) =





Therefore, the required general solution of the given differential equation is
