BIG IDEAS

UNDERSTANDING THE STANDARD

2016 VDOE Curriculum Framework - T.7 Understanding

·  The trigonometric function values of any angle can be found by using a graphing utility.

·  The inverse trigonometric functions can be used to determine angle measures whose trigonometric function values are known.

·  Calculations of inverse trigonometric function values can be related to the triangular definitions of the trigonometric functions.

·  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.71  Use a graphing utility to determine the trigonometric function values of any angle in either degrees or radians.

·  T.72  Define inverse trigonometric functions.

·  T.73  Determine angle measures by using the inverse trigonometric functions when the trigonometric function values are given.
