Question

How does A compare to B?

A. Cos (0+2π)
B. Cos (-0)
a. A is greater than or equal to B
b. A is less than or equal to B
c. A = B
d. Cannot be determined

Answer 1

A is equal to B because both have the value of 1.

Step-by-step explanation:

The given question is comparing the values of two trigonometric functions. The first one is Cos (0+2π) and the second one is Cos (-0). Let's evaluate each function step by step to compare them.

1. For the first function, Cos (0+2π), we know that the cosine function has a period of 2π. So, adding 2π to 0 does not change the value. Therefore, Cos (0+2π) is equal to Cos 0, which is 1.
2. For the second function, Cos (-0), we know that cosine is an even function, which means that Cos (-θ) is always equal to Cos θ for any angle θ. In this case, Cos (-0) is equal to Cos 0, which is also 1.

Therefore, both functions have the same value of 1, and we can conclude that A is equal to B (A = B).
