### BIG IDEAS

### UNDERSTANDING THE STANDARD

2016 VDOE Curriculum Framework - T.4 Understanding

· Trigonometric functions are not invertible, because they are periodic. Domain restrictions on trigonometric functions are necessary in order to determine the inverse trigonometric function.

### ESSENTIALS

**The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to**

·
T.4_{1}** Determine**
the domain and range of the inverse trigonometric functions.

·
T.4_{2}** Use**
the restrictions on the domains of the inverse trigonometric functions in **determining** the values of the inverse trigonometric
functions.

·
T.4_{3}** Graph**
inverse trigonometric functions.
