The function f(t) = 30 sin (t) −15 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?

-15 indicates that the median of the wave is located there. To find the minimum and maximum, add or subtract half of 30, which is the number before the sine.

min = -30

max = 0

A normal sine function such as this one has a period of 2π, so that is the amount of time (in hours) that one cycle takes.

Understanding what? lol
