Other Trigonometric Functions. y = tan x. Passes thru (0,0); increases from left to right; has asymptotes @ 90, 270, …. y = cot x. X-intercepts @ 90, 270; decreases from left to right; has asymptotes @ 0, 180, 360, …. y = csc x.

y = csc x has asymptotes @ 0, 180, 360, …; vertex of u-shape @ 1 and -1 y = sec x Crosses the y-axis; has asymptotes @ 90, 270, …; vertex of u-shape @ 1 and -1
y = 7 tan x y = tan x By including a number for a, the graph becomes narrower. (If the a value is less than 1, the graph would be wider)
y = 3 csc x y = csc x By including a number for a, the graph becomes narrower. (If the a value is less than 1, the graph would be wider). ALSO on sec and csc, the vertex of the graph shifts to ± a. (keep in mind if there is also a vertical shift that will move the graph up/down accordingly)
