1. The problem statement, all variables and given/known data

I cannot get my head around these equations...
$$\dot{x}(t)=-sin y(t)$$

$$\dot{y}(t)=-\frac{cos x(t)}{sin x(t)} cos y(t).$$

They are to be solved with integration by quadratures. :S But I am not at all familiar with that technique and I can't find any tutorial for it.

Since I have never heard about it before i can't make an attempt either! :(
