To write: A equation of cosine function whose graph is shown below.
The equation of cosine curve is written as
Given:
The graph of the cosine function is shown below.
Concept used:
The cosine curve is of the form
Calculation:
In order to write the equation of cosine function, evaluate the missing parameters using the concept stated above. Therefore, the maximum and minimum values of the function are
And the curve repeats itself after the interval from
And using the result for period of the function.
Now
And the curve of the graph starts from
Conclusion:
The equation of cosine curve is written as
