Sorry to ask these questions again but I just need some ideas on this one or a solution
THe body mass of a squirrel living in the will varies during a year, and is given by m=4+cos[(pi t)/6] where (m) kg is the squirrel's body mass (t) months after 1 August.
B) For what length of time will the squirrel's body mass remain above 4.7kg
pi time t in the brackets
Thanks once again
