Newton

In order to accurately describe gravity, Newton invented the mathematics of calculus.

Sir Isaac Newton

Sir Isaac Newton invented calculus, based on functions, for more complex shapes and numbers.

Newton and Leibnitz

Progress occurs when a few people happen to have a fortunate coincidence of concepts in their heads so that, like a lucky genetic roll-of-the-dice, the combination turns into a really new idea: Newton and Leibnitz inventing the calculus, John Nash coming up with game theory, a bunch of folks figuring out how to mass-produce firearms and automobiles, etc.

Isaac Newton both

Isaac Newton first developed calculus via an infinitesimal quantity called a fluxion.

by Isaac Newton 1646–1716

Calculus was invented, more or less simultaneously, by Isaac Newton (1642–1727) and Gottfried Leibniz (1646–1716).

by Issac Newton

Issac Newton invented calculus with just a pencil and Jack Kelley's brain,' Kelley said.

Isaac Newton and other scientists

When the simple algebra equation couldn’t be useful in solving complex difficulties, Isaac Newton and other scientists developed calculus.

Leibniz and Sir Isaac Newton, an English scientist,

Leibniz and Sir Isaac Newton, an English scientist, independently developed calculus.

as Isaac Newton

The ‘inventor’ of Calculus is often credited as Isaac Newton but

a young Isaac Newton

To address them, and to calculate things like the exact amount of time between sunrise and sunset for a westward traveler without computing an infinite number of terms, a young Isaac Newton developed calculus.
