The 2 is only there because the circumference of a circle is pi*D, and D = 2*r Link to comment Share on other sites More sharing options...

Like we can read on Wikipedia coefficient can be any mathematical expression. Both variable and number. https://en.m.wikipedia.org/wiki/Coefficient Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

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 Share Posted November 9, 2020 ! Moderator Note Rule 12: (emphasis added) We expect arguments to be made in good faith.

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.
