CuriosOne Posted November 9, 2020 Posted November 9, 2020 To start off: when we use 2pi*r = circumference.. Is 2 a coefficient? Or is it a natural number?

That's another reason why I asked, What is the point of calculus???? Were given this information by ""scientst"" Edited November 9, 2020 by CuriosOne

They are only accurate/true if you put d/dx in front of the left side. 29 minutes ago, CuriosOne said: If a function "any function" starts with a coefficient a coefficient has "NO EFFECT" on the process of differentiation.. That's another reason why I asked, What is the point of calculus???? The derivative is taken ( in this case ) only with respect to the variable x , because y=f(x). If the coefficient, c, was another variable of the function, say y=f(x,c), then partial derivatives would be involved Also, why do you have a problem with the coefficient being a natural number?
swansont Posted November 9, 2020 Posted November 9, 2020 ! Moderator Note Rule 12: (emphasis added) We expect arguments to be made in good faith. Honest discussions, backed up by evidence when necessary. Example of tactics that are not in good faith include misrepresentation, arguments based on distraction, attempts to omit or ignore information, advancing an ideology or agenda at the expense of the science being discussed, general appeals to science being flawed or dogmatic, conspiracies, and trolling.
