Brace yourself for a thrilling journey into the mystical world of Inverse Secant calculations! Prepare to have your mind bent, twisted, and turned inside out. If you’re not on the edge of your seat, you’re in the wrong place.
Inverse Secant Calculation Formula
The Inverse Secant (sec^-1) of a number is calculated by finding the arcsecant (arcsec) of that number. Here’s how the formula looks when translated into the magical language of Python:
import math
def inverse_secant(x):
return math.acos(1/x)
