Here is the second method of drawing graph.
This method requires transformation from the most basic graph y = sin x or y = cos x.
We need to do the transformations in this order.
1. The frequency
2. The magnitude of the amplitude
3. The signage of the amplitude
4. The vertical shift is always LAST
We must draw the graphs in each stage from 1 to 4 (plus the starting graph y = sin x or y = cos x) for a total of 5 graphs.
This transformation method is particularly useful in future studies (especially in the A Levels if you are taking A Levels).

Just sin and cosine?
The most common are sine and cosine. Tangent is very easy to remember (you only need to remember the number of cycles).
