1. Consider the following function that describes the position the amount of cases of in- fluenza c(t) = 10 sin(t). Where c is the amount of cases in 10,000 people and t given in months. Take the derivative of the function, give proper units, and describe the results and what they mean. 2. Find f'(r) for each functions. (a) f(x) = VI+25/3 +x+1 (1) (b) f(x) = (x'+ 2x)(e* + 1) (2)
