Math Problem Statement

Use a calculator to find the following. Round your answer to four places past the decimal point. cot 36°.

Solution

The question asks to find the value of cotangent for the angle 36 degrees and round the answer to four decimal places.

To find cot(36)\cot(36^\circ), you can use the relationship:

cot(36)=1tan(36)\cot(36^\circ) = \frac{1}{\tan(36^\circ)}

Using a calculator:

  1. Find tan(36)\tan(36^\circ).
  2. Take the reciprocal of that value to get cot(36)\cot(36^\circ).
  3. Round the result to four decimal places.

Let's calculate this value:

tan(36)0.7265\tan(36^\circ) \approx 0.7265

cot(36)=10.72651.3764\cot(36^\circ) = \frac{1}{0.7265} \approx 1.3764

So, the value of cot(36)\cot(36^\circ) rounded to four decimal places is 1.3764.
