# What are the important information needed to graph y = tan (3x + pi/3)?

Nov 11, 2015

Basically, you need to know the shape of the graphs of Trigonometric functions.

#### Explanation:

Alright.. So after you've identified the basic shape of the graph, you need to know few basic details to completely sketch the graph. Which includes:

1. Amplitude
2. Phase shift (Vertical and Horizontal)
3. Frequency/Period.

The labeled values/constants in the above picture is all the information you need to plot a rough sketch.

Hope that helps,
Cheers.
