Aim: How do we differentiate Inverse Trig functions? Do Now: Does y = sin x have an inverse? yes, but only in restricted domain.
Definition of Inverse Trig Functions alternate notation arcsinx sin-1 x ‘the angle whose sin is . . .’
Graphs of Inverse Trig Functions y = arccsc x y = arcsec x y = arctan x
1 0 UND. 1 however, restricted domain Evaluating Inverse Trig Functions ‘the angle whose sin is -1/2’ reference angle of /6 sin is negative in QIII and IV angle y is - /6
1 0 UND. 1 however, restricted domain Evaluating Inverse Trig Functions ‘the angle whose cos is 0’ reference angle of /2 angle y is /2
1 ‘the angle whose tan is ’ 0 UND. 1 however, restricted domain Evaluating Inverse Trig Functions reference angle of /3 angle y is /3
Using Inverses to Solve an Equation take tan of both sides inverse property x = 2 solve for x
Using Right Triangles Given y = arcsin x, where 0 < y < /2, find cos y. Since y = arcsin x, then sin y = x 1 x opposite y
Using Right Triangles Since y = arcsec x, then sec y = x opposite 1 y 2 adjacent

Algebraic Transcendental Logarithmic Exponential Trigonometric Inverse Trigonometric Polynomial Rational Functions w/radicals Elementary Functions Elementary functions have proven sufficient to model most phenomena in physics, chemistry, biology, engineering, economics, etc. An elementary function is a function from the following list or one that can be formed as a sum, product, quotient or composition of functions in the list.
