GOAL: define inverse trigonometric functions

BELL WORK: is this the same?

The inverse function of an exponential f(x) is … Answer ahead

It is convenient to think of a value of an inverse trigonometric function of aas an angle

Remember Paula and the table for ICFES know the trig. f(x) of exact or special angles(read the table backwards, knowing the trig f(x) find the angle)

Try graphing with your calculator sin-1 x Remember: angles in radians

Only between domain [

'restricted sine f(x)'

The book says now a horizontal line test

NEW LEARNING: the inverse sine (or arcsine ) function
