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

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