Answer:
The given expressions simplifies to tan (4x).
Step-by-step explanation:
Here, the given expression is : 
By TRIGONOMETRIC IDENTITY:

Putting this identity here, and taking A = 9 x, B = 5 x, we get

= tan(4x)
Hence, the given expressions simplifies to tan (4x).
Suggestion:
The width is the x value and the hight is the y value.
Plot the points on the graph as decimal if that helps.
The point at the bottom left is the origin (0,0)
I hope this helps.
