Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.

Question

6. The number of online buyers in Western Europe grew steadily over the past decade. The
function P(t) = 28.5 + 14.42 In(t) (1<t<7) gives the number of online buyers as a
percentage of the total population, where t is measure in years, with t= 1 corresponding
to 2001.
a). What was the percentage of online buyers in 2001? How fast was it changing in 2001?
b). What was the percentage of online buyers in 2007? How fast was it changing in 2007?
