Plural gradients

gradient (plural gradients)

Wikipedia has an article on: Gradient
  1. A slope or incline.
  2. A rate of inclination or declination of a slope.
  3. (calculus) Of a function y = f(x) or the graph of such a function, the rate of change of y with respect to x, that is, the amount by which y changes for a certain (often unit) change in x.
  4. (physics) The rate at which a physical quantity increases or decreases relative to change in a given variable, especially distance.
  5. (vector algebra) A vector operator that maps each value of a scalar field to a vector equal to the greatest rate of change of the scalar. Notation for a scalar field φ: φ

In vector calculus, the gradient of a scalar field is a vector field which points in the direction of the greatest rate of increase of the scalar field, and whose magnitude is the greatest rate of change.

A generalization of the gradient for functions on a Euclidean space which have values in another Euclidean space is the Jacobian. A further generalization for a function from one Banach space to another is the Fréchet derivative.

How do you work out gradient?
Q. I know i must sound like a complete idiot, but i can't work out gradient on a line graph. The line is straight, but sloping upwards. Please can you help me? I need a simple answer because I've looked on here for similar questions and the answers are really confusing! Thanks!

A. You don't sound like an idiot at all. In fact, as a highschool maths tutor, I often get questions like this. The answer, while simple, is not that straightforward. In fact there are a number of ways to calculate the gradient of a linear equation (i.e. a straight line) depending on what you have to work with. I will list three: 1) If you know the angle made with the positive x direction, then you can calculate the gradient by taking the tangent of that angle. E.g. M = tan(60) 2) If you know the general equation to the line (Y = Mx + c) it is simply the coefficient of the independent variable, the M. 3) If you know 2 points on the line (and since you have a graph of the line, you can choose ANY two points you like!) you can work out… [cont.]

How do I make a colored radial gradient text in Photoshop CS3?
Q. I am trying to make my text with a radial gradient, with the middle lighter than the outside, and it's red. Every time I try to set a gradient overlay, it changes it to black and white! I also tried the gradient tool, and I got it to stay red, but it won't give it a radial gradient, even though I told it! I'm very frustrated, someone please help me!

A. Click the gradient tool then on top click once on the gradient. It should open up a pop up menu. Just double click the colors on the slider and change them.
