Algebra 2: Chapter 14, Section 1

Graph Sine, Cosine, and Tangent Functions

[LarissaFord]

when, if ever, would the range of a tangent function go from higher to lower along the x line instead of lower to higher? I understand that the range of tangent functions are all real numbers. Thank you for these videos. we had MCAs this week so we had to cover 14.1 and 14.2 in one day and I got lost along the way.
