Chapter 5: Problem 13

Use a calculator to approximate the value. Round your answer to two decimal places. \(\operatorname{arcsec} 1.269\)

Short Answer

Expert verified
The approximate value of \(\operatorname{arcsec} 1.269\), rounded to two decimal places, will be the result of the calculation explained above. Please remember to use your own calculator to determine the result.

Step by step solution

01

Convert from secant to cosine

The secant is the reciprocal of the cosine function. So, \(\operatorname{arcsec}(1.269) = \arccos\left(\frac{1}{1.269}\right)\).
02

Use a calculator

Now, use a calculator to find the value of \(\arccos\left(\frac{1}{1.269}\right)\). Remember to set your calculator to radian mode because by default, most calculators use degrees.
03

Round to two decimal places

Once you have the answer from your calculator, round this number to two decimal places.
