Evaluate tan(40)

Problem

tan(40)

Solution

1. Identify the angle and the trigonometric function. The task is to evaluate the tangent of 40 degrees.

2. Determine if the angle is a standard value on the unit circle. Since 40 is not a standard angle (like 30 45 or 60, an exact radical form is not commonly used.

3. Calculate the numerical value using a calculator set to degree mode.

4. Round the result to a standard number of decimal places (typically four).

Final Answer

tan(40)≈0.8391
