It may have been simple for Newton.
But then again, he invented calculus.
But then again, he invented calculus.
He did - but, in a way, he didnt. Liebnitz invented calculus independently, and if you tried to understand Newtons calculus from his writings after having learned calculus in school, you would be in trouble - because Liebnitz notation is what you learned in school.Reason being, that Newtons notation isnt as elegant and understandable as Liebniz.
In the era following the publication of calculus by those two, you assigned credit for the invention of calculus to Newton or to Liebnitz according to whether you were pro or anti British.
So Brit students learned Newtonian calculus notation until Charles Babbage, as an undergraduate, led a successful revolt in favor of Liebnitz notation.
Blaise Pascal invented calculus along with a guy name Ferme. Newton might have made some important contributions...I’m not sure.
