On the (mis)use of formula sheets. (English)
N. Z. Math. Mag. 45, No. 2, 14-15 (2008).
The author discusses an example of student errors that typically occur while using trigonometric formulas for their work with matrix representations of plane geometric transformations, thus pointing out that students must have practice in using formula sheets, rather than merely using them during examinations.
