fridge temp equation: T(x)=3sin(pi/10x)+36 What are the high and low temps that will occur in the fridge after its been chilled to 36 degrees? How many mins between these temps? What is the period length?
Amplitude of your trig curve is 3, so
max temp is 39, min is 33 ....(36+3 and 36-3)
period = 2π/(π/10) = 20 minutes
time between high and low = 10 minutes
