Answer:
Step-by-step explanation:
Given
The attached graph
Required
The constant rate of change (m)
This is calculated as:
From the graph, we have:
So, the formula becomes:
This is the concept of trigonometry, the sine, cosine and tangent of 11/6 pi radians will be as follows;
11/6pi=11/6*180=330
thus;
tan 330=-0.5774
sin 330=-0.5
cos 330=-0.8660
