Express /u as a function of and if = ln(2 + 2), = cos(2 + 4), and = 5. Use the multivariable chain rule and make sure your answer is in terms of and . No need to simplify, so long as your answer is in terms of and and all derivatives have been taken.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
