              Deriving the Equation of Tangents

              Students learn how to find the equation of a tangent using the gradient of the radius and touching coordinates.  As learning progresses they apply their learning to prove whether a line is tangential.
              Differentiated Learning Objectives
              • All students should be able to calculate the gradient of a tangential line to a circle.
              • Most students should be able to calculate the equation of a line tangential to a circle.
              • Some students should be able to use algebra to prove a line is tangential to a circle.
