(x-1)²sin²(arctanx) built geometrically

This file contains a geometric diagram with (x-1)²sin²(arctanx) as a square at its centre. This square was built using fundamental geometrical principles related to SOH CAH TOA, CHO SHA CAO and Pythagoras' theorem.This file is suitable for students studying higher level geometry at college or university. It was constructed with care using a pair of compasses and a ruler.

(tanθ-cotθ)² built geometrically

This file contains a geometric diagram with (tanθ-cotθ)² as a square at its centre. This square was built using fundamental geometrical principles related to SOH CAH TOA, CHO SHA CAO and Pythagoras' theorem. With this diagram it becomes clear as to why tan²θ-2tanθcotθ+cot²θ=(tanθ-cotθ)². This file is suitable for students studying higher level geometry at college or university. It was constructed with care using a pair of compasses and a ruler.
