paragraph_text: Inverse trigonometric functions
  
  Because the six main trigonometric functions are periodic, they are not injective (or, 1 to 1), and thus are not invertible. By restricting the domain of a trigonometric function, however, they can be made invertible.
  
  The names of the inverse trigonometric functions, together with their domains and range, can be found in the following table:
