Slope (Gradient)

Finding the slope of lines on the Cartesian plane

lesson notes:02 gradient

Distance & Midpoint

Finding the distance between points and the midpoint of the points using Cartesian geometry techniques

The beauty of using vectors is that problems in 3D are not that different to problems in 2D

Pushing our cartesian geometry formulas from 2D to 3D

Sometimes our knowledge of the quadratic function can be used to solve projectile motion problems
