Calculus

Differential Equations

Differential equations are in some sense the “reason for being” of the calculus, with the Fundamental Theorem of Calculus being one solution of the most basic differential equation: given dy/dx = f (x), what is y = F(x)? This unit examines some specific examples of the differential equations (leading to the exponential and logarithmic functions) as well as the important numerical technique of Euler’s Method for approximating solutions to differential equations. Other lessons consider some specific differential equations arising in the context of science.
