WebThe Laplace equation is a second-order partial differential equation that describes the distribution of a scalar quantity in a two-dimensional or three-dimensional space. The Laplace equation is given by: ∇^2u (x,y,z) = 0, where u (x,y,z) is the scalar function and ∇^2 is the Laplace operator. What kind of math is Laplace? WebExample 1: Solve the second order differential equation y'' - 9y' + 20y = 0 Solution: Since the given differential equation is homogeneous, we will assume the solution of the form y = e rx Find the first and second derivative of y = e rx: y' = re rx, y'' = r 2 e rx. Next, substitute the values of y, y', and y'' in y'' - 9y' + 20y = 0. We have, citycons
