Simple Trig. Equations - Tarsia (Year 12 Maths)

A Tarsia puzzle that covers “simple” Trig. Equations such as 4 sin x = 1. A few of the equations require knowledge of the identity tan x = sin x / cos x.

Students solve the equations and match them up to the answers on another piece. When completed, all the pieces join up to make a hexagon. As space on the puzzle pieces was limited, I’ve used a code to tell students the range in which they are looking for solutions. For example, if an equation is followed by (A), they are looking for all solutions between 0 and 360 degrees. You will need to display the code on the board whilst students complete the puzzle.

I wasn’t able to upload the Tarsia file, just a pdf copy of the puzzle pieces, so you won’t be able to edit the task, sorry.
