Solve the following differential equations:


Answer :

Now separating variable x on one side and variable y on another side, we have,


– cot(x) dx = sec2y cot(y) dy


Integrating both sides we get,




Sin2x = 2 sinx cosx




Using identities:



and



– log| sinx | = log| tany |+ c


Using: log(a)+log(b) = log(ab)


log( sin x tan y) = log c


sin(x) tan(y) = c
