L3.5 Deriving Trig Derivatives

Susan Braford, Mathematics Instructor
Kings Fork High School, Suffolk

Susan Braford created this power point presentation for a classroom activity. The students derived the differentiation rules for the 6 trig functions by using the graphs of sine and cosine, their graphing calculators and what they knew of the reciprocals an ratios. Once they discovered d/dx of sin x was cos x, they then used the quotient rule to discover csc x. She was able to roam about the room with her wireless mouse and monitor their progress. It was the first time she tried this and everything went better than anticipated.
