BQ#4 - Unit T - Concept 3

Why is a normal tangent graph uphill, but a normal tangent graph downhill?

In the Unit Circle ratios of a tangent graph, it is sin(x) over cosin(x) which is the same as y/x. On the graph for tangent, when cosine or x equals 0, which is 90 and 270, there is an asymptote. Because there is an asymptote in those areas, the graph is uphill.

In the Unit Circle ratios for a cotangent graph, it is the reciprocal of tangent, meaning the raio is x/y. On the graph for cotangent, when sine or y equals 0, which is 0 and 180, there is an asymptote. Because there is an asymptote in those areas, the graph is downhill.
