Inverse Trigonometric Functions Quiz

What is the result of switching the input and output values in an inverse trigonometric function?

• A complex number

• A logarithmic value

• A new trigonometric function

• An angle measure

How can the inverse of a trigonometric function be expressed?

• With a -1 superscript or 'Arc' prefix

Why must the domain of trigonometric functions be restricted to define their inverses?

• To ensure the output values are complex

• To prevent repeating output values

• To make the function continuous

• To increase the range of the function
