Question

Use a calculator to find the approximate value of arccos(0.36).

Answer 1

Answer:

Answer for arccos(0.36) is 68.8998°

Step-by-step explanation:

The arccosine function is the inverse function of cos(x).

arccos(a) = cos-1(a)

 

For example, the cosine of 30° is 0.866

cos(30°) = 0.866

Then, the arccos of 0.866 is 30°

arccos(0.866) = cos-1(0.866) = 30°

Given, arccos (0.36)

So we need to find inverse function value of cos (0.36)

= cos-1(0.36)

=68.8998°

Answer for arccos(0.36) is 68.8998°
