In our view, the core material for the (non-remedial) courses defined by these tomes is but a shadow of that traditionally covered material in a reasonable high school program. Moreover, much of the material is substantially repeated from earlier study and it proceeds at a slow pace with extensive practice and

Poincar´e’s Disk Model for Hyperbolic Geometry

This result is now know as the Saccheri-Legendre Theorem (Theorem 7.3). He was unable to arrive at a contradiction when he looked at ... Note that this arc is clearly orthogonal to Γ by its construction. ... The hyperbolic trigonometric functions cosh(x) and sinh(x) are defined by: sinh(x) = ex −e−x 2 cosh(x) = ex +e−x 2 and tanh(x ...
