william oughtred -lrb- 5 march 1574 -- 30 june 1660 -rrb- was an english mathematician and anglican minister .
he was alive during the jacobean age .
after john napier invented logarithms and edmund gunter created the logarithmic scales -lrb- lines , or rules -rrb- upon which slide rules are based , it was oughtred who first used two such scales sliding by one another to perform direct multiplication and division ; and he is credited as the inventor of the slide rule in 1622 .
oughtred also introduced the '' × '' symbol for multiplication as well as the abbreviations `` sin '' and `` cos '' for the sine and cosine functions .
