The first of two RISP activities, Radians and Degrees, students are set the task of finding an angle whose sine value is the same whether measured in radians or degrees. Solving the problem leads to further discussion about the relationship between radians and degrees and general trigonometric equations.
The second, Generating the Compound Angle Formula, requires students to generate a function given certain components and graph the resultant function. The activity leads to the compound angle formulae for sine and cosine.
