Lines t=+-kpit=±kπ, k = 1, 2, 3, 4,..., parallel to s-axis.

Explanation:

As t to0_(+-), sto8t0±,s8.
Here, 0_+-0± indicate the approaches for limit, from either side.

As t to+-kpi_(+-), sto+-oot±kπ±,s±, k = 1, 2, 3,...
Here, kpi_(+-)kπ± indicate the approaches for limit, from either side.

So, the asymptotes are the lines t=+-kpit=±kπ, k = 1, 2, 3, 4,..., parallel to s-axis

To understand the approaches fpr limits and limits better, recall that sine is positive in the first two quadrants and negative in the third and fourth.
