How do you solve second order difference equations?
y = ert (A cost+ B sint). These are the steps you need to know. For homogeneous second order differential equation, simply move to the auxiliary equation, find the value of lambda λ, write the solution of y and then find the constants using initial conditions if required.
Can we solve second order differential equation?
Second order differential equations can be solved using different methods such as the method of undetermined coefficients and the method of variation of parameters. The solution of a non-homogeneous second order differential is the sum of the complementary and particular solution and is given as y = yc + yp.
What is a second order differential equation?
A second order differential equation is one that expresses the second derivative of the dependent variable as a function of the variable and its first derivative. (More generally it is an equation involving that variable and its second derivative, and perhaps its first derivative.)
