In Example 5, change sec 27.82° to csc 27.82° and then find the value.

Data from Example 5

To find the value of sec 27.82°, we use the fact that

sec 27.82° = (cos 27.82°)^-1 = 1.131

Either of the above two options can be evaluated on a calculator to obtain the result 1.131, which has been rounded according to Table 4.1.
