The procedure for Method A is as follows: (1) find the interval from the Autumnal Equinox to the Vernal Equinox; (2) the planet's period of revolution; (3) evaluate the interval from the perihelion to the first crossing of the latus rectum; (4) evaluate the interval from the perihelion to the aphelion; (5) set the ratio of (1) to (2) equal to the ratio of (3) to (4); and finally, (6) solve the resulting transcendental equation graphically to yield the eccentricity.
A performance like this made it very easy to underestimate the rigours of a programme that unwittingly exposed the delicacies of an unaccompanied Bach Siciliano and Jeremy Pike's abstract and austere Aphelion to the tedium generated by Sutton Coldfield Philharmonic Society's opening 'housekeeping' announcements, and closed with a daunting stylistic leap from Bruch to Gershwin, and stamina-sapping encores.
