Find a unit normal vector to the surface at the given point. Hint: Normalize the gradient vector \Delta F(x, y, z). Surface: \ln (\frac{x}{y - z})= 0 Point (1,10, 9) Find the normal vector to the surface {z^2} = {x^2} - {y^2} at...
To add a gradient to text in Illustrator evenly, you need to turn your group into one vector shape. Open the Pathfinder panel and click the Unite button, and then turn the resulting shapes into a compound path (Object > Compound Path > Make or Control-8)....
Vector gradients are made up of mathematical algorythms that are maybe too complex for a non-Postscript printer to interpret. "Is there a way, inside of illustrator, to add noise/dithering in Illustrator to a defined gradient? In hopes of avoiding stupid people talking about...

This article is mainly concerned with the gradient as it relates topartial derivatives. If you want an introduction to slopes, see:what is a slope?You can also find somesimple examples of finding a gradient (slope)below. Gradient vs Derivative and The Gradient Vector ...
A vector field is mathematically described as a function where each input variable point is assigned a vector in the same dimensional space as the point. Mathematically, the point will be represented as {eq}P = (x,y,z) {/eq} and the vector field corresponding to the point will be ...
Since we want the two shapes to behave as a single larger one, we’ll have to turn them into a Compound Shape by going over to Pathfinder’s advanced menu and then clicking on the Make Compound Shape option. Step 3 Next, we’ll want to apply a linear gradient to the Compound Shape...
So, I have (x, y, z) values of these points. I also have a vector of v which is the pressure values of these points. Now, I want to determine the pressure gradient of each point. The function `gradient()` might help, but it seems that it it just for very even datasets. I ...

In this tutorial, I'll show you how to draw a vector illustration step by step, proving to you that drawing using Illustrator is not as scary as it may seem!
