Textbook Question

In Exercises 39–48, use a calculator to find the value of the trigonometric function to four decimal places.
tan 32.7°

Verified step by step guidance

Identify the trigonometric function to evaluate, which is the tangent of 32.7 degrees, written as \(\tan 32.7^\circ\).

Make sure your calculator is set to degree mode since the angle is given in degrees, not radians.

Input the angle 32.7 into the calculator and then use the tangent function key to find \(\tan 32.7^\circ\).

Read the value displayed on the calculator, which is the tangent of 32.7 degrees.

Round the result to four decimal places as required by the problem.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Understanding the Tangent Function

The tangent of an angle in a right triangle is the ratio of the length of the opposite side to the adjacent side. It is a fundamental trigonometric function that relates an angle to a ratio of sides, often used to find slopes or angles in various applications.

Using a Calculator for Trigonometric Functions

Calculators can compute trigonometric values directly when the angle is input in the correct mode (degrees or radians). For this problem, ensure the calculator is set to degree mode before calculating tan 32.7°, to obtain an accurate decimal value.

Rounding to Four Decimal Places

After calculating the trigonometric value, rounding to four decimal places means limiting the result to four digits after the decimal point. This ensures precision and consistency in answers, which is important for clarity and comparison in mathematical problems.
