Answer:
If NN represents an angle, and you want to express \cos(NN)cos(NN) as a fraction in simplest terms, it depends on the specific value of NN. The cosine function returns different values for different angles.
Step-by-step explanation:
For example, if NN is a common angle like 30 degrees, 45 degrees, or 60 degrees, we can provide the simplified fraction. Could you specify the value of NN so I can assist you further?
