Differential Equations

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?

The processing of raw sugar has a step called “inversion” that changes the sugar’s molecular structure. Once the process has begun, the rate of change of the amount of raw sugar is proportional to the amount of raw sugar remaining. If 1000 kg of raw sugar reduces to 800 kg of raw sugar during the first 10 hours, how much raw sugar will remain after another 14 hours?
