This worksheet is a mix of the two previous worksheets. Finish these two sheets before you start with this one!
1) Make you familiar with the worksheet and try it out! 2) Can you find any special points e.g. intersections points of Sine and Cosine or Sine and abscissa? Note them down! 3) In the privious wokrsheet you found out that Tanget isn't defined for Phi equals 90° and 270°. What does this mean for the functional corellation of Tangent?
