Please answer without using previously posted answers. Thanks Let F(x, y) be a two-dimensional vector field. Spose further that there exists a scalar function, o, such that Then, F(x,y) is called a g...
Please describe the contour map and list important aspects of it, thanks! Let f(x,y) -2(xy 1) be a scalar function in R2. a) Find the vector field F(x, y) for which f(x, y) is a potential function, b) c) sketch a contour map of f (x, y) and, on the same figure, sketch F(x,y) (on R2). Comment on any important aspects of your sketch. Let f(x,y) -2(xy 1) be a scalar function in R2. a) Find the vector field F(x,...
For any vector field F⃗ and any scalar function f we define a new field a) Assuming that the appropriate partial derivatives are continuous, show the following formula: b) Let ⃗x = x⃗i + y ⃗j + z ⃗k and the vector field Use the formula found in a) to answer the following question: is there a number p such that F⃗ is incompressible (that is, its divergence is zero)? f F)(x,y,z) = f(x,y,z)F(x,y, z) We were unable to transcribe...
a) A vector field F is called incompressible if div F = 0. Show that a vector field of the form F = <f(y,z),g(x,z),h(x,y)> is incompressible. b) Suppose that S is a closed surface (a boundary of a solid in three dimensional space) and that F is an incompressible vector field. Show that the flux of F through S is 0. c)Show that if f and g are defined on R3 and C is a closed curve in R3 then...
