Great question! When A=3, your second and fourth key points in step #2 will be vertically stretched by a factor of 3 - so in your example, you would have the points (pi/8, 3) and (3pi/8, -3). Here's a link to another tangent graphing example with a leading coefficient of A=2: ruclips.net/video/oIaZxsm1pzY/видео.html Hope this helps!
Thank you!!!
What if they have value of y like y=3 tan(2×)
