Question

Sketch the graph of the tangent curve y = tan 2x in the interval from 0 to 2pi

Answer 1

correct answer: a.

Explanation:

y = tan2x graph should have right side headed up, because it's positive.

however, the graph's frequency should be changed.

Since the normal period of y = tan x graph is pi/|b|,

the period for this graph should be pi/2.

We can see that graph (a) is meeting all the needs.
