Inverse exsecant

Inverse exsecant (or Arcsecant) is a way to figure out the angle of a triangle. When you are given two sides of a triangle, like the length of two sides of a right triangle, you can use inverse exsecant to figure out the angle of the corner between the two sides. Inverse exsecant takes the length of the two sides, and finds the angle between them. Imagine the corner of a triangle, then imagine a line on the corner. Inverse exsecant is like measuring how far that line is from the corner.
