A program is an executable code, which serves some computational purpose. Software is considered to be a collection of executable programming code, associated libraries and documentations. Software, whenContinue reading “Software Engineering”

1. The order and degree of the differential equation. y +dy/dx =1/4∫ y .dx are-: 1. We have dy/dx + dy/dx= 1/4 .∫ y.dx ⇒ dy/dx +d^2 y/dx^2 =1/4 y [on differentiating w.r.t. x ] Differential equation is of order 2 and degree 1. 2. Example (x+1)dy/dx= 2xy {variable separable method} We have, (x+1)dy=2xy dxContinue reading “Differential equations”
