Essay

Sales of computers are subject to seasonal fluctuations. Computer City's sales of computers in 1995 and 1996 can be approximated by the function
​ $s ( t ) = 0.445 \sin ( 1.37 t + 1.75 ) + 0.712 ( 1 \leq t \leq 6 )$ ​
where ​t is time in quarters ( $t = 1$ represents the end of the first quarter of 1995) and $s ( t )$ is computer sales (quarterly revenue) in billions of dollars. Estimate Computer City's maximum and minimum quarterly revenue from computer sales.
​
Maximum sales __________ billions of dollars
​
Minimum sales __________ billions of dollars
