In mathematics, linear differential equations are differential equations having solutions which can be added together in particular linear combinations to form further solutions. Such an equation is said to have order n, the non exact differential equation example with solution pdf of the highest derivative of y that is involved.
A typical simple example is the linear differential equation used to model radioactive decay. 0 is called a homogeneous equation and its solutions are called complementary functions. When the Ai are numbers, the equation is said to have constant coefficients.
