This concept is one of the easier ones that come under Integral Calculus. It is generally covered after area under curves. Differential Equations are one of the direct applications of indefinite and definite integrals. 1 First Order Diﬀerential Equations • Diﬀerential equations can be used to explain and predict new facts for about everything that changes continuously. • d2x dt2 +a dx dt +kx = 0. • t is the independent variable, x is the dependent variable, a and k are parameters. • The order of a diﬀerential equation is the highest deriviative Differential Equations Keywords: Differential Equations Created Date: 3/7/2014 8:57:23 AM 1.
