                                      Where u is the value of a trig function of angle v  

                

              Properties of Inverse Functions

It is important to note that depending on your book,:

• Inverse Sine

or

                         y= tan x                                                          y= arctan x

S.O.S!

   When given an angle of inverse sine or inverse tangent, the angle value is restircted to the first and fourth quadrents.  This will help a lot when solving equations.  When given an inverse cosine, the angle is within the first and second quadrents.  Here is an image Mr. Bruns gave us to Help:

 Hope this helps! 6 days till the return of Wilhelm! AHH!
