a) To get start to control the temperature the values of parameter a, b, c and d which given in equation 3.2 should be determined, solve the equation to find required values. b) Use compound angle identities to separate the temperature wave equation into distinct component waves to find the value of temperature in March. And the equation of monitoring the temperature in the factory is given by: T(t)= a cos(b(t-d)) + c............................. Eq. 3.2 Where case "2" Monitoring quality of the machines in production line.
