Chapter 4: Problem 24

Use a calculator to evaluate the expression. Round your result to two decimal places. $$\arccos (-0.7)$$

Short Answer

Expert verified
Your answer will depend on the output of your calculator after rounding to two decimal places. For instance, if your calculator gave an answer of 135.5845 to \(\arccos(-0.7)\), your rounded answer would be 135.58.

Step by step solution

01

Understanding the function

The inverse cosine function, denoted as \(\arccos(x)\) or \(\cos^{-1}(x)\), is used to determine the angle whose cosine is \(x\). In this exercise, we want to find the angle whose cosine is -0.7.
02

Evaluating \(\arccos(-0.7)\)

Using a scientific calculator, input -0.7 into the \(\arccos\) function. Ensure your calculator is set to the appropriate mode (degrees or radians) depending on your exercise or preference.
03

Rounding Off the Result

Upon evaluating \(\arccos(-0.7)\) in the calculator, round off the obtained result to two decimal places as per the requirement of the exercise.
