What is Wronskian?
Wronskian method is a process in which you determine whether the linear differential function or differential equation is linearly dependent or independent on linear algebra. The wroniskan method is represented with the symbol “W''.
For f1, f2,...fn functions, it uses the differential and determinate matrix method in which if the wronskian method solution is non zero then your function is linearly independent. On the other hand, if the given function solution is zero then the function is linearly dependent.
Formula of Wronskian:
The wronskian method formula is based on the function differentiation f1(x), f2(x),…, fn(x) and the determinate matrix where you put the function and solve it.
$$ W(f_1, f_2,..., f_n)(x) \;=\; \left(\begin{matrix} f_1(x) & f_2(x) & \cdots & f_n(x) \\ f_1’(x) & f_2’(x) & … & f_n’(x) \\ \vdots & \vdots & \ddots & \vdots \\ f_1^{(n-1)}(x) & f_2^{(n-1)}(x) & \cdots & f_n^{(n-1)}(x) \end{matrix} \right) $$
How to Calculate the Wronskian?
For the calculation of Wronskian of a set of linear functions, the wronskian determinant calculator uses the determinant method to find whether a set of functions is linearly independent. Here's a stepwise guide on how to calculate the Wronskian manually:
Step 1:
Identify the linear functions f1(x), f2(x),…,fn(x) and variable of differentiation.
Step 2:
Find the first derivative of each function fi(x), calculate fi′(x), fi′′(x),…,fi(n − 1)(x).
Step 3:
According to the numbers of functions, add the differential function value f`(xi) and the linear differential function f(xi) of determinate matrix. For example, 2 by 2 determinant matrix for wroiskan is:
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} f_1 (x) & f_2(x) \\ f_1’(x) & f_2’(x) \\ \end{matrix} \biggr| $$
Step 4:
Solve the determinant whether the given matrix is 2 by 2 determinate or 2 by 3 determinant matrix.
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} f_1(x) & f_2(x) \\ f_1’(x) & f_2’(x) \\ \end{matrix} \biggr| \;=\; f_1(x) . f_2’(x) - f_2(x) . f_1’(x) $$
Step 5:
After simplification, you get the solution of the Wronskian method problem which determines whether the linear function is independent or dependent.
Solved Example of Wronskian Method:
A solved example of the Wronskian method is given below to understand how the Wronskian calculator with steps works.
Example: Find the wronskian of the following:
$$ f_1 \;=\; x^2 + 4,\; f_2 \;=\; sin(2x) $$
Solution:
The given function is,
$$ f_1 \;=\; x^2 + 4,\; f_2 \;=\; sin(2x) $$
Differentiate the function f1(x) and f2(x) with respect to x.
$$ \frac{d}{dx} (x^2 + 4) \;=\; 2x $$
$$ \frac{d}{dx} (sin(2x)) \;=\; 2\; cos (2x) $$
As the given function has 2 by 2 matrix so the require determinant matrix become,
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} f_1(x) & f_2(x) \\ f_1’(x) & f_2’(x) \\ \end{matrix} \biggr| $$
Now make a determinate matrix and put the linear function and derivative function value,
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} x^2 + 4 & sin(2x) \\ 2x & 2\;cos(2x) \\ \end{matrix} \biggr| $$
Solve the determinant matrix as per the rule of matrix determination,
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} f_1(x) & f_2(x) \\ f_1’(x) & f_2’(x) \\ \end{matrix} \biggr| \;=\; f_1(x) . f_2’(x) - f_2(x) . f_1’(x) $$
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} x^2 + 4 & sin(2x) \\ 2x & 2\;cos(2x) \\ \end{matrix} \biggr| \;=\; 2x^2 cos (2x) - 2x\; sin(2x) + 8\; cos(2x) $$
The result of given linear differential function using wronkisan method is,
$$ W (f_1, f_2)(x) \;=\; 2x^2\; cos(2x) - 2x\; sin(2x) + 8\; cos(2x) $$
