Graph a tangent function (y = 3tan(2x))

Graph y=3 tan⁡2x for −π/4 less than x less than 3π/4 .

Recall:
• The tangent function is odd
• It is undefined at odd multiples of x=π/( 2 ) (vertical asymptotes)
• Unlimited range

Step 1: Find two consecutive asymptotes between −( π )/2 and ( π )/2
Step 2: Identity the coordinates of the midway point.
Step 3: Find the x-coordinates 1- and 3-quarters away from the start.
