Why {x^n} /\sum_{0}^{x}x^{n-1}={x-1}/x: Explained

AI Thread Summary

The equation {x^n} /\sum_{0}^{x}x^{n-1}={x-1}/x raises questions regarding the absence of "n" in the summation. Concerns are highlighted about the left side being non-zero at x=1, while the right side equals zero at the same point, indicating a potential inconsistency. The discussion suggests that further clarification or explanation from the original source is needed to resolve these discrepancies. Participants express skepticism about the validity of the exercise as it stands. Overall, the equation's formulation appears problematic and requires additional scrutiny.

It doesn't look sound to me.If you sum over "x",why doesn't "n" appear in the equation...?

Also, in its current form, the Right Side is 0 at x=(1), whereas the Left Side is non-zero at x=(1).

There's definitely something weird with this exercise.Maybe he'll explain it,or or just drop it...

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
