Match the following definitions with the correct word

• Arctangent

• The ----------- of a positive number is the acute

  angle whose tangent is that number.

• Arcsine

• The --------- of a number between 0 and 1 is the

  acute angle whose sine is that number.

• Arccosine

• The ---------- of a number between 0 and 1 is the

  acute angle whose cosine is that number.

The best strategy for creating a(n) ​ (a)   function is to switch the x and the ​ (b)  

• inverse

• y

• cosine
