Question

How do you graph `y=1/4 tanx` and include two full periods?

Answer 1

See graph and details.

Explanation:

`y = 1/4 tan x in ( - oo, oo )`, sans asymptotic

`x = (2 k + 1 ) pi/2, k = 0, +-1, +-2, +-3, ...`.

The period is `pi`.,

Graph for two periods, `x in ( - pi, pi )`:
graph{(y-1/4 tanx)=0[-3.14 3.14 -1.57 1.57]}
