A handwritten mathematical derivation on a lined notebook page shows the simplification of the trigonometric identity -6/√7 + 2/√7 × tan²(4π/7) = csc³(π/7). The steps involve algebraic manipulation and substitution, relating to properties of a regular heptagon with side length 'a', diagonals 'b' and 'c', and circumradius 'R'.
-6/√7 + 2/√7 × tan²(4π/7) = csc³(π/7)
This relation is from the regular heptagon where a = side length, b = short diagonal, c = long diagonal & R = circumradius.
