What is the Wronskian?
The Wronskian is a mathematical determinant used to determine the linear independence of functions within a given set. The Wronskian is a determinant used in mathematics to check whether a set of functions is linearly independent or dependent. It is commonly applied in differential equations and linear algebra.
If the Wronskian is non-zero, the functions are independent (they do not form a linear combination).
If the Wronskian is zero, the functions are dependent (at least one function can be expressed as a linear combination of the others).
What is a Wronskian Calculator?
The Wronskian Calculator is an online tool that helps compute the Wronskian of given functions by calculating their derivatives and evaluating a determinant. A calculator is a math tool that finds the Wronskian determinant for a group of functions. But what is a Wronskian? It’s a number that helps show if a group of functions is independent from one another. This idea is important in many fields, like math, physics, and engineering.
- The Wronskian is a determinant that helps determine whether a set of functions is linearly independent.

Definition of the Wronskian
The Formula
The Wronskian of n functions f₁(x), f₂(x), …, fₙ(x) is defined as:
W(f₁, f₂, …, fₙ) = | f₁ f₂ … fₙ | | f₁’ f₂’ … fₙ’ | | f₁” f₂” … fₙ” | | … … … … | | f₁⁽ⁿ⁻¹⁾ f₂⁽ⁿ⁻¹⁾ … fₙ⁽ⁿ⁻¹⁾ |
Where f’ denotes the first derivative, f” the second derivative, and so on.
Examples
Let’s explore two examples to see how a Wronskian calculator works its magic in calculating the Wronskian of the set.
1: Simple Exponential Functions
Consider the functions f₁(x) = eˣ and f₂(x) = e²ˣ.
Wronskian calculation: W(f₁, f₂) = | eˣ e²ˣ | | eˣ 2e²ˣ | = eˣ · 2e²ˣ – e²ˣ · eˣ = 2e³ˣ – e³ˣ = e³ˣ ≠ 0
Since the Wronskian is non-zero, these functions are linearly independent.
2: Trigonometric Functions
Let’s take f₁(x) = sin(x) and f₂(x) = cos(x).
Wronskian calculation: W(f₁, f₂) = | sin(x) cos(x) | | cos(x) -sin(x) | = sin(x) · (-sin(x)) – cos(x) · cos(x) = -sin²(x) – cos²(x) = -(sin²(x) + cos²(x)) = -1
The constant non-zero Wronskian indicates these functions are linearly independent for all x.
A step-by-step explanation of how the Wronskian determinant is calculated.
Example 3
Arrange functions and their derivatives in a determinant.
2: Compute derivatives of each function.
3: Evaluate the determinant to find the Wronskian.
Example:
f₁(x) = eˣ and f₂(x) = e²ˣ.
W(f₁, f₂) = | eˣ e²ˣ | | eˣ 2e²ˣ |
Final Answer: e³ˣ/0, meaning the functions are linearly independent.
What is the General Form of the Wronskian Matrix?
The Wronskian matrix is constructed as follows:
- The first row contains the original functions.
- The second row contains the first derivatives.
- The third row contains the second derivatives.
- This pattern continues until the (n−1)th(n-1)^{th}(n−1)th derivative.
- The determinant of this matrix is the Wronskian value.
If the determinant is non-zero, the functions are independent. If zero, they are dependent.
How does the Wronskian determine linear independence?
The Wronskian helps in determining if a set of functions is linearly independent or dependent:
- If W ≠ 0, the functions are independent (none can be written as a combination of the others).
- If W = 0, the functions are dependent (at least one function is a linear combination of others).
This is crucial in differential equations for finding unique solutions.
What happens if the Wronskian is zero?
If the Wronskian = 0, the functions are linearly dependent. This means:
- At least one function can be expressed as a linear combination of the others.
- The functions do not form a fundamental set of solutions for differential equations.
- Additional tests may be needed to confirm dependence, as sometimes a zero Wronskian does not guarantee dependence in all cases.
