Consider  , where
, where ![x \in [-1,1]](https://tex.z-dn.net/?f=x%20%5Cin%20%5B-1%2C1%5D) .
.
This means there exists a ![\theta \in [0, \pi]](https://tex.z-dn.net/?f=%5Ctheta%20%5Cin%20%5B0%2C%20%5Cpi%5D) such that
 such that  and
 and  .
.
Thus, taking the inverse cosine of both of these equations, we get that:
 .
.
Subtracting arccos(x) from both sides, we get the required result.

Answer:
Multiply (2 * 16)
Step-by-step explanation:
Our expression is 13 - 2 * 16 + 2. The two operations used here are addition (+) and multiplication (*).
Remember order of operations PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
We see that multiplication comes before addition, so we multiply 2 by 16 first:
13 - 2 * 16 + 2
13 - 32 + 2
Thus, the answer is multiply.
