Amongst other things they independently invented calculus. Newton probably made the first discovery, but delayed publishing for many years. Leibniz also held off publishing for a long time, waiting, apparently for Newton to do it. Eventually Leibniz published anyway. They became bitter rivals.
Gottfried Wilhelm Leibniz
both were the mathematician who develop the finite intgral method
As a scientist, he is mainly known for the general law of gravitation, and Newton's laws of movement. As a mathematician, he basically invented calculus (so did another mathematician, Leibniz, independently of Newton).
Not a theory, They discovered a branch of math called calculus.
Principally, calculus, although Leibniz had independently discovered the theory. Newton is also credited with the infinite convergent series (showing that there is no exact value for PI), and with Newton's Method, for extracting roots of equations.

No, Newton, an Englishman, and Leibniz, a German, were both accomplished mathematicians, who independently developed an early form of calculus.
Isaac Newton and Gottfried Wilhelm Leibniz
Both of them came up with the concept (semi-) independently; both were aware that the other was working on it and in fact they exchanged letters on the subject, but they approached it from different directions (Newton started with differentiation, Leibniz started with integration). Going by their private papers it appears that Newton was further along earlier than Leibniz, but Leibniz published a full description much earlier than Newton did.

Gottfried Wilhelm Leibniz
Isaac Newton and Gottfried Wilhelm Leibniz are credited with inventing calculus independently of each other around the same time. Each used his own notation. Calculus is more commonly associated with Newton than with Leibniz.
Yes, although Newton did contribute.
