Find the Exact Value cot(-4)

Problem

cot(−4)

Solution

1. Identify the property of the cotangent function as an odd function, which states that cot(−x)=−cot(x)

2. Apply the odd function property to the given expression to move the negative sign outside the function.

3. Determine the exact value. Since 4 is not a standard reference angle (like π/6 or π/4, the exact value is expressed in terms of the cotangent function itself.

Final Answer

cot(−4)=−cot(4)
