Trigonometry Refresher





Workshop Description

This workshop provides a refresher on the fundamentals of right angled trigonometry. Topics covered will include:

  • degree and radian measure, and how to convert from one to the other
  • determining sine, cosine and tangent ratios of special angles, without using your calculator!
  • representing angles on the unit circle, and using the coordinate system to find trigonometric ratios
  • determining the angle of interest, given one or more trig ratios


Designed For: In particular, this is a new workshop created for students in MA121 & MA122to help with the material on polar representation of a complex number. Calculus students from MA100, MA101and MA110 may also be interested. And as always, any WLU registered student is welcome to attend.



Dates/Times Offered (Fall Term 2012): TBA
