show me the graph of y=tan2x, step by step and how to solve keypoints
-------
If x = 0, tan(2x) = tan(0) = 0
So plot a point at (0,0)
----
Now draw a tangent curve thru that point.
----
To make the plotting of other points easy, let x be pi/4 , x = -pi/4
y = tan(2(pi/4)) = tan(pi/2) = 1 give you point (pi/4,1)
y = tan(2(-pi/4) = tan(-pi/2) = -1 gives you point (-pi/4,-1)
