Which of the following has the same value as cos 3pi

Option C : has the same value as

Explanation:

It is given that to find the same value as from the 4 options.

Now, we shall find the value of

The value of is -1.

Thus, the value of is -1.

Option A :

Using the identity ,

Since, the value of is 0. Thus, we have,

Hence, the value of is undefined.

Thus, the value of is not the same as value of

Therefore, Option A is not the correct answer.

Option B :

The value of is undefined.

Thus, the value of is not the same as value of

Therefore, Option B is not the correct answer.

Option C :

Since, Substituting, we have,

Thus, the value of is the same as the value of

Therefore, Option C is the correct answer.

Option D :

Rewriting the angles,

Simplifying, we get,

The value of is undefined.

Thus, the value of is not the same as the value of

Therefore, Option D is not the correct answer.
