A vector field on [math]\mathbb{R}^3[/math] is a function that assigns to each point [math]\left(x,y,z\right)[/math] a three-dimensional vector [math]F\left(x,y,z\right)[/math].[br][br]1. Change the components of the vector field by typing, for example:[br][br] [math]P=[/math] x^2sin(y) [math]Q=[/math] sqrt(y^2+z)exp(x/y) [math]R=[/math] log(x-y+z)[br][br]2. Change the [b]Scale[/b] to provide a better visualisation of the vector field.
