A bird species in danger of extinction has a population that is decreasing exponentially (A=A0ekt). Five years ago the population was at 1800 and today only 1000 of the bird are alive. once tha population drops below 200, the solution eill be irreversible. When will this happen? The population will drop below 200 birds approximately __years from now.

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.
