Odd One Out

We are asked to compute . Recall that and . Thus: Using the identity , we can write: Therefore: Thus, the value of is .

1. Use the trigonometric identity for complementary angles. The identity for cotangent is: 2. This identity directly gives us the result. Therefore, the correct answer is:

Step 1: Use the complementary angle identity.
We know that: This simplifies the expression to: Step 2: Express .
Since , we can substitute: Step 3: Conclude the result.
Thus, the value of is .

Step 1: Recall the value of .
We know that . Step 2: Substitute the value of .
Substituting into the given expression, we get: Step 3: Conclude the result.
Thus, the value of is .
