Tutorial Exercise
Consider the differential equation
x²y" - 6xy' +10y = 0; x², x5, (0, ∞o).
Verify that the given functions form a fundamental set of solutions of the differential equation on the indicated interval.
Form the general solution.
Step 1
We are given the following homogenous differential equation and pair of solutions on the given interval.
x²y" - 6xy' +10y = 0; x², x5, (0, 0)
We are asked to verify that the solutions are linearly independent. That is, there do not exist constants c₁ and c₂, not both zero, such that c₁x² + ₂x³ = 0. While this may be clear for these solutions
that are different powers of x, we have a formal test to verify the linear independence.
Recall the definition of the Wronskian for the case of two functions f and f₂, each of which have a first derivative.

f₁ f₂
By Theorem 4.1.3, if W(f₁, f₂) = 0 for every x in the interval of the solution, then solutions are linearly independent.
Let f₁(x) = x² and f₂(x) = x5. Complete the Wronskian for these functions.
