3. Velocity vector is given as V=(1+t)xi + (2+t)yj, find the equation of (a) Streamline,
(b) Pathline
(c) Streakline,
Given that the common point for all three is x=1, y=2, and z=0 at t=0.

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
