Question

The function f(t) = 20 sin (t) + 12 models the temperature of a periodic chemical reaction where t represents time in hours. What are the maximum and minimum temperatures of the reaction, and how long does the entire cycle take?

Answer 3

at max or min, the change of f wrt is 0, differentiate the functions and you get, 20cost(t)=0, and that means that t=90 or 270, when t=90, f(t)=32. that is the max, when t=270, f(t)=-8, that is the minimum

Answer 4

how about the Period?
