Chapter 4: Problem 32

Use a calculator to evaluate the expression. Round your result to two decimal places. $$\arctan 2.8$$

Short Answer

Expert verified
The precise value of \(\arctan 2.8\) varies depending on the calculator but it should be approximately 1.24 when rounded to two decimal places.

Step by step solution

01

Use a Calculator

Input \(\arctan 2.8\) into your calculator, ensuring that it is in radian mode.
02

Interpret Result

The calculator will provide a value which represents the arctan of 2.8 in radians.
03

Round to two decimal places

The final step is to round this result to two decimal places. Keep in mind that if the third decimal is 5 or more, you round up; if it's 4 or less, keep the number as it is.
