The temperature of an oven can be modelled by the equation T = 225 0.3 sin

Question:

The temperature of an oven can be modelled by the equation T = 225 − 0.3 sin (2x − 3), where T is the temperate in Celsius and x is the time in minutes after the oven first reaches the desired temperature, and angles are measured in radians.

a. State the minimum temperature of the oven.

b. Find the times during the first 10 minutes when the oven is at a minimum temperature.

c. Calculate the time when the oven first reaches a temperature of 225.2 °C.
