This worksheet is designed to help students with the topic of calculating the six trigonometric functions (often referred to as cofunctions -- the cofunction of the sine is the cosine, the cofunction of the secant is the cosecant, and the cofunction of the tangent is the cotangent.)
I start out class with the student notes page (1 page), which has several examples of what today's lesson will be about. Once we finish doing the notes together, I have them get to work within their groups on this worksheet (2 additional pages).
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
