Overview
Differential equations are mathematical equations that involve derivatives of functions and are fundamental to describing rates of change in various fields like physics, chemistry, biology, and economics. This chapter introduces the basic concepts of differential equations, their classification, met
Key Concepts
A differential equation is an equation
A differential equation is an equation that contains derivatives of a function. Examples include dy/dx = cos x, d²y/dx² + k²y = 0. The equation relate
Order is the highest derivative present
Order is the highest derivative present (e.g., d²y/dx² means order 2). Degree is the power of the highest order derivative when the equation is polyno
Process of creating differential equations by
Process of creating differential equations by eliminating arbitrary constants through differentiation. For y = ax², differentiate to get dy/dx = 2ax,
Method where variables x and y
Method where variables x and y can be separated to opposite sides: f(x)dx = g(y)dy. Integrate both sides separately. Example: dy/dx = xy becomes dy/y
Equations where all terms have
Equations where all terms have the same degree when expressed as polynomials in x, y, and dy/dx. Solved using substitution y = vx or x = vy. Example:
