The mass of the first x meters of a thin rod is given by the function m(x) on the indicated interval. Find the linear density function for the rod. Based on what you find, briefly describe the composition of the rod.
1) m(x) = 4x – sin x grams for 0 ≤ x ≤ 6

2) m(x) = 4x grams for 0 ≤ x ≤ 2

@bahrom7893  can u help?

bahrom7893 · Answer

Sorry I have no idea what linear density function is. @Mertsj might now.

bahrom7893 · Answer

I want to say it's just the integral of m(x), but I might be very wrong

anonymous · Answer

okay

bahrom7893 · Answer

I got it backwards, it's the derivative.

yes.

"without citing..."

mertsj · Answer

Hunt it up yourselves then.

anonymous · Answer

Never mind ya'll I think I got it.

anonymous · Answer

Find dm/dx for each situation.

1) dm/dx = 4 - cos(x) for 0 ≤ x ≤ 6

2) dm/dx = 4 for 0 ≤ x ≤ 2

anonymous · Answer

ok lol

@onegirl

anonymous · Answer

there is a formula you use hold on let write it up

anonymous · Answer

$$p(x1) = \lim_{x \rightarrow x1} = f(x) - f(x1)/x - x1 = f'(x1) $$

anonymous · Answer

wow its so much simpler then it seems to be thank god!
