Introduction

Differential Equation refers to all the equation that relates a function with its derivatives. [1] Different forms of differential equations are found in various different areas, including engineering, physics, economics, biology, etc. For example, the motion of pendulum can be expressed in the form of differential equation, 2 2 + sin = 0, [2] where both the function of θ and the second derivative of θ are both in a single equation.

Rationale

From when I was in elementary school, I read a book that was about elementary physics knowledge. Then, I saw that when a parachute is falling, the time the parachute reaches the terminal velocity is actually dependent on lots of factors. Then, I always wondered what factors would be determining the time it takes for a parachutist to reach the terminal velocity. After, I read a book, which said the parachutist’s velocity and the acceleration when falling can be expressed in a form of differential equation. Therefore, I chose to explore the topic of parachute motion. As I have wondered it, I will be investigating some key factors that would determine the time it takes for the parachutist to reach the terminal velocity, and to do that, I will be researching on the first order differential equations and their solutions, as I was truly interested on differential equations when I was searching their definitions and examples, and the expression of the motion of the parachutist is also a first order differential equation…
