Short Answer

How would you show that a given vector field in 2 is not conservative?

A given vector field in 2 is not conservative when, F(x,y)f(x,y)fxi+fyj

See the step by step solution

Step by Step Solution

Step 1.Given Information

How would you show that a given vector field in 2 is not conservative?

Step 2. A vector field is conservative 

If a vector field can be described as a gradient, it offers a number of mathematically appealing properties, including the ability to be easily integrated along curves. Such fields are referred to as conservative vector fields.

A vector field that is conservative. F is a vector field that represents the gradient of a function f.

Step 3. A conservative vector field F is a vector field that can be written as the gradient of some function f.

That is,

F(x,y)=f(x,y)=fxi+fyj

Hence, we can say that a given vector field in 2 is not conservative, when

F(x,y)f(x,y)fxi+fyj
