BQ#5: Unit T Concept 1-3

Why do sine and cosine NOT have asymptotes, but the other four trig graphs do? Use unit circle ratios to explain.

-Sin and Cosine do not have asymptotes because they can never be undefined. Both have a denominator of "r" which always is qual to 1. The only way to get undefined values in ratios is to have a denominator of zero. For Cosecant, Secant, Tangent, and Cotangent, those have asymptotes because its possible for them to have a zero as the denominator unlike Sin and Cosine.
