Can someone please help?
The temperature in a room is controlled by an electronic thermostat. The temperatures vary according
to the sinusoidal function: = 6 sin[90( − 11)] + 19, where y is the temperature (°C) and x is the
time in hours past midnight.
a) What are the maximum and minimum temperatures in the room?
b) At what time does the temperature first hit 13 °C?
