You cannot enter it on the calculator but you can use the relation arcsec(z) =arccos(1/z)
On your calculator arccos is represented as cos^-1.
Here is a screen capture from a calculator that has the function. The arcos is computed along with the arcsec for angles in radians (top 2 lines) and in degrees (bottom two lines).
