From London, Scott entered St John's College, Cambridge where he studied the Mathematical Tripos. He was fourth Wrangler in the Tripos in 1875 and, two years later, was elected to a fellowship at St John's College. He was an Assistant Master at Christ's Hospital from 1877 to 1879 during which time he wrote his only mathematics book The theory of determinants and their applications which was published in February 1880. Scott's Preface reads:-
In the present treatise I have attempted to give an exposition of the Theory of Determinants and their more important applications. In every case where it was possible I have consulted the original works and memoirs on the subject; a list of those I have been able to see is appended as it may be useful to others pursuing the same line of study. At one time I hoped to make this list exhaustive, supplementing my own researches from the literary notices in foreign mathematical journals, but even with this aid I found that it would be necessarily incomplete. In consequence of this the list has been restricted to those memoirs which I have seen, the leading results of which are incorporated either in the body of the text or in the examples.Scott then studied law, becoming a Barrister in 1880, and a Bencher of Lincoln's Inn in 1922. He was Senior Bursar of St John's College from 1883 to 1908 when he was appointed as Master of St. John's College, Cambridge. Scott held this post for the rest of his life. He was also Vice-Chancellor of the University of Cambridge for the years 1910-12.
The principal novelty of the treatise lies in the systematic use of Grassmann's alternate units, by means of which the study of determinants is, I believe, much simplified.
I have to thank my friend Mr James Barnard, M.A. of St John's College and Mathematical Master at the Proprietary School, Blackheath, for the care he has bestowed on correcting the proofs and for many valuable suggestions.
On 1 January 1904 a second paperback edition of Scott's book The theory of determinants and their applications was published. The book was revised for this second edition by G B Mathews and on the title page Scott is described as Robert Forsyth Scott, M.A., of Lincoln's Inn, Fellow of St John's College Cambridge. He also published History of St John's College (1907) and wrote many papers on College History. Scott's entry in Who's Who lists his recreations as: formerly rowing; antiquarian and biographical pursuits. It also list his club as the Athenaeum, and gives his address as The Master's Lodge, St John's College, Cambridge.
