Gradients

Thinking about steepness, parallel and perpendicular linesThe concept of steepness, or Gradient, is a fundamental idea that underpins ideas from linear functions to Calculus! Its important to look at this bit of coordinate geometry here so we can relate it to work on perpendicular bisectors, their properties and Voronoi diagrams. It is often the case that you re expected to deduce the gradients and equations of perpendicular...
