1755 – Switzerland
‘Analytical calculus – the study of infinite processes and their limits’
Swiss mathematician. His notation is even more far-reaching than that of LEIBNIZ and much of the mathematical notation that is in use to-day may be credited to Euler.
The number of theorems, equations and formulae named after him is enormous.
Euler made important discoveries in the analytic geometry of surfaces and the theory of differential equations.
Euler popularised the use of the symbol ‘Π‘ (Pi); e , for the base of the natural logarithm; and i , for the imaginary unit.
Euler is credited with contributing the useful notations f (x) , for the general function of x ; and Σ , to indicate a general sum of terms.
