Question

use a calculator to find \\( \arccos (0.968) \\).
\\( \arccos (0.968) \approx \square \\)
(round to the nearest thousandth as needed. type your answer in radians.)

Explanation:

Step1: Set calculator to radian mode

Ensure the calculator is in radian mode (since the answer needs to be in radians).

Step2: Calculate arccos(0.968)

Use the calculator's arccos function (usually labeled as \( \cos^{-1} \)) to input 0.968. The calculator computes \( \arccos(0.968) \approx 0.259 \) (after rounding to the nearest thousandth).

Answer:

\( 0.259 \)
