   # Wronskian The Wronskian of two differentiable functions f and g , denoted by W (f, g), is defined as the function given W ( f , g ) = | f g f ' g ' | . The function f and g are linearly independent when there exists at least one value of x for which W ( f , g ) ≠ 0 . In exercise 71-74, use the Wronskian to verify that the two functions are linearly independent. y 1 = e a x y 2 = e b x , a ≠ b ### Multivariable Calculus

## Wronskian The Wronskian of two differentiable functions f and g, denoted by W (f, g), is defined as the function given W ( f , g ) = | f g f ' g ' | .The function f and g are linearly independent when there exists at least one value of x for which W ( f , g ) ≠ 0 . In exercise 71-74, use the Wronskian to verify that the two functions are linearly independent. y 1 = e a x y 2 = e b x ,     a ≠ b

To determine

To verify:

The two function y1=eaxandy2=ebx,ab are linearly independent by using Wronskian Method.

### Explanation of Solution

Given information:

The given function are y1=eaxandy2=ebx,ab.

Concept Used:

The Wronskian of two differentiable functions f and g, denoted by W (f, g), is defined as the function given by the determinant W(f,g)=|fgf'g'|.

Proof:

First, find the derivative of the y1andy2 with respect to x, we get

y1'=aeaxandy2'=bebx

Now, we have to find the determinant W(y1,y2)=|y1y2y1'y2'|
