What is Wronskian?
The Wronskian method is a process in which you determine whether the linear differential function or differential equation is linearly independent or dependent in 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 given function differentiation f1(x),f2(x),…,fn(x) and the determinate matrix where you put the function and solve it as shown in the below formula.
$$ W(f_1, f_2,..., f_n)(x) \;=\; \left(\begin{matrix} f_1(x) & f_2(x) & \cdots & f_n(x) \\ f_1’(x) & f_2’(x) & … & f_n’(x) \\ \vdots & \vdots & \ddots & \vdots \\ f_1^{(n-1)}(x) & f_2^{(n-1)}(x) & \cdots & f_n^{(n-1)}(x) \end{matrix} \right) $$
How to Calculate the Wronskian Determinant Calculator?
For the calculation the Wronskian of a set of linear functions we use the determinant method to find whether a set of functions is linearly independent. Here's a stepwise guide on how to calculate the Wronskian by hand which are given as:
Step 1:
Identify the linear functions f1(x),f2(x),…,fn(x) and variable of differentiation.
Step 2:
Find the first first derivatives of each function fi(x), calculate fi′(x),fi′′(x),…,fi(n−1)(x)
Step 3:
Add the differential function value f`(xi) and the linear differential function f(xi) in the determinate matrix according to their number of functions. 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 gives you a clear idea about the Wronskian calculator with steps so that you don't become confused in its calculation process.
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 values 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 after putting the given linear differential function,
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} f_1(x) & f_2(x) \\ f_1’(x) & f_2’(x) \\ \end{matrix} \biggr| \;=\; f_1(x) . f_2’(x) - f_2(x) . f_1’(x) $$
$$ W (f_1, f_2)(x) \;=\; \biggr|\begin{matrix} x^2 + 4 & sin(2x) \\ 2x & 2\;cos(2x) \\ \end{matrix} \biggr| \;=\; 2x^2 cos (2x) - 2x\; sin(2x) + 8\; cos(2x) $$
The result of given linear differential function using wronkisan method is,
$$ W (f_1, f_2)(x) \;=\; 2x^2\; cos(2x) - 2x\; sin(2x) + 8\; cos(2x) $$
