Trigonometric Inverses Changing the domain L. Marizza A. Bailey

Definition of Inverse Let Then f has an inverse g if and only if Calculus Lesson 13 12/4/2018 Definition of Inverse Let Then f has an inverse g if and only if Then if and is a function if and only if each y is assigned to only one x L. Marizza A. Bailey

Definition of Inverse is a function if and only if each y is assigned to only one x This function is not invertible. This means it does not have and inverse

Definition of Inverse is a function if and only if each y is assigned to only one x This function is invertible. This means it does have and inverse

Sine is not invertible The sine function is not invertible on the real line If we change the domain to , then it will be invertible.

sin-1 (x) = arcsin(x) The domain of arcsin is the range of sin The range of arcsin is the domain of sin Note the domain and range

cos-1(x) = arccos(x) What is the domain of invertibility of cosine? Write the cosine function with domain and range of invertibility? Write the arccosine function with domain and range of invertibility?

The domain of invertibility of Sine Which of these angles generates same y-coor? Not in domain

The domain of invertibility of Cosine
