Question 856754
How do I graph this function over a 2-period interval? Can you explain step by step please? 
The function is y = 3 + 1/2 tanx
----------------------
{{{graph(400,400,-6,6,-10,10,3 + (1/2)tan(x))}}}
--------------------------------------------------
Graphing:
If x = 0, y = 3
If x = pi/6, y = 3+sqrt(3)/3 = 3.577
If x = pi/3, y = 3+sqrt(3) = 3 + 1.73 = 4.73
If x = -pi/6, y = 3.577
If x = -pi/3, y = -4.73
--------------------------------
