7-6 The Inverse Trig FunctionsObjectives:1. Find values of inverse trig
functions.
f(x) = tan x is not one-to-one, so it has no inverse.
Tangent
However, with restricted domain of
we create F(x) = Tan x
which does have an inverse.
Inverse Tangent
Find Tan-1(-1) in radians with and then without a calculator.
Example 1
For G(x) = Sin x we restrict the domain to
Inverse Sine
For H(x) = Cos x we restrict the domain to
Inverse Cosine
Find Cos-1(-0.5) w/out a calc.
Example 2
Find each w/out a calc.Sin-1(-1)
