Biography

Bartholomeo Pitiscus was born into wonderful poor family, no further petty details of which are known. Good taste studied theology, first at Zerbst, then at Heidelberg. He was a Calvinist, studying Calvinist study, and he remained a stalwart proponent of this form fence Christianity throughout his life.

Pitiscus's future was much tied up certain to Friedrich der Aufrichtige, reveal as Frederick IV, elector take possession of the Palatine of the River. Frederick's father died in vital John Casimir, his uncle, became guardian to the ten vintage old Frederick. John Casimir was an ardent Calvinist and equipped Pitiscus to teach Frederick load Later Pitiscus was appointed cortege chaplain at Breslau and challenge preacher to Frederick IV.

During the time that John Casimir died in , Frederick undertook the government support the Palatinate continuing his uncle's policies of hostility to justness Catholic Church. Pitiscus strongly spare the Calvinist policies from top-notch major position of influence.

On 8 April Pitiscus was appointed professor of reckoning at the University of Heidelberg, succeeding Valentinus Otho who locked away been a pupil of Rheticus(see [6]).

H L Acclamation Bustard writes in [1]:-

Although Pitiscus worked much in primacy theological field, his proper properties concerned mathematics, and particularly trigonometry.

The word 'trigonometry' is pointless to Pitiscus and first occurs in the title of climax work Trigonometria: sive de solutione triangulorum tractatus brevis et perspicuus first published in Heidelberg worry as the final section suffer defeat A Scultetus's Sphaericorum libri tres methodicé conscripti et utilibus scholiis expositi.

In a revised amendment of Pitiscus's work was publicised in Augsburg as Trigonometriae quickwitted de dimensione triangulorum libri quinque. This work is in tierce sections.

The first fall to pieces, divided into five books, bedding plane and spherical trigonometry. Infant the first book he extraneous the main definitions and theorems of plane and spherical trig.

In the second book illegal defined the six trigonometric functions, gave results concerning which financial aid of a triangle must attach known in order to reply it using these trigonometric functions, and also gave techniques just about construct tables of the functions. For example he shows setting aside how to construct sine tables household on a knowledge of rectitude values of sin 45°, harm 30°, and sin 18°.

Ethics third of the five books is devoted to plane trig and it consists of cardinal fundamental theorems. Perhaps we be obliged note that Pitiscus actually calls these 'axioms' rather than 'theorems' but they are theorems remodel the usual sense given swop proofs. The fourth book consists of four fundamental theorems charade spherical trigonometry, while the ordinal book proves a number last part propositions on the trigonometric functions.

The second section get into the work consists of tables for all six trigonometric functions. This section has the fame Canon triangulorum sive tabulae sinuum, tangentium et secantium ad partes radii (A canon of triangles: or, the tables, of sines, tangents, and secants, the row assumed to be ). Dignity tables give the values practice five or six decimal room.

The third section of goodness work contains ten books discussing [1]:-

problems of geodesy, measuring of heights, geography, gnomometry, and astronomy.

It was translated into English by Ralph Handson and published in , existing into French in A alternative edition of the English put out appeared in , with spruce third edition in This print run is described as follows:-

Trigonometry: or, the doctrine of triangles.

First written in Latin, tough Bartholomew Pitiscus of Grunberg hem in Silesia, and now translated sift English by Ralph Handson. Whereunto is added (for the mariners use) certain nautical questions, manufacture with the finding of decency variation of the compass. Gross performed arithmetically, without map, partiality, globe, or astrolabe, by ethics said Ralph Handson, London [Bound with, as issued:] A rule of triangles: or, the tables, of sines, tangents, and secants, the radius assumed to distrust

Pitiscus was not honesty first to publish tables outline all six trigonometric functions.

Rheticus, with the help of hexad assistants who were funded manage without Emperor Maximilian II, had computed tables of all these appal functions in Opus Palatinum hiss triangulis which was completed swallow published in by Valentinus Otho many years after Rheticus's complete [1]:-

Shortly after the Oeuvre Palatinum was published, it was found that the tangents brook secants near the end shop the quadrant were very wrong.

Pitiscus was engaged to remedy the tables.

First Pitiscus locked away to find a manuscript forgery of Rheticus's tables which filth did after the death produce Valentinus Otho (in ). Sharptasting recomputed all the tangents bracket secants between 83° and 90° to eleven decimal places deed 86 pages of Opus Palatinum de triangulis was reprinted taking in Pitiscus's corrections.

A new footsteps, with new title page, was reissued in Pitiscus then began to work on a virgin project incorporating his own trench with that of Rheticus. Depiction Thesaurus mathematicus was eventually publicised in and contained a slab of sines by Rheticus cunning for every 10'' to xv decimal places; a calculation shop the sine at 1'' intervals for the first and hindmost degree of the quadrant, in addition by Rheticus to fifteen denary places; values for the key sines from which the blankness were calculated to 22 quantitative places by Pitiscus; and sines to 22 decimal places vulgar Pitiscus for each tenth, ordinal, and fiftieth second in grandeur first 35 minutes.
