The average temperature, in °F, for Atlanta, GA is modeled by the sinusoidal function

y = 18.25 sin(pi/6 t - 2.09) + 61.15

where t is the time in months and January is t = 1.

What is the average temperature for the month of February?

How do I do this problem ?
Please Help

since Feb ---> t = 2
sub that in, make sure your calculator is set to radians

y = 18.25 sin ((π/6)(2)-2.09) + 61.15
= 45.39

make sure to follow the order of operation.
