    Error Formula
AI Thread Summary
The discussion revolves around finding the error formula for the equation y = x^5. Participants express confusion about the concept of "error formula" in this context and seek clarification. It is noted that when multiplying two numbers, their fractional errors are added, referencing the multiplication rule for propagating uncertainties. The specific application of this rule to the function y = x^5 is questioned, particularly how to express the error in terms of x. The conversation highlights the need for a clearer understanding of error propagation in mathematical equations.

i have no idea what the heck this means :confused: :

Give the error formula for y=x5


Can someone help me?

edit- sorry misread what you were asking.

If you multiply two numbers then you add their fractional errors.

If this is a textbook problem, what is the textbook? I've never heard of "the error formula" for a mathematical equation.
 
so what should i write for the answer, because i am clueless right now.
 
You apply the multiplication rule for propagating uncertainties.

Y = x5

Any ideas about what multiplying may be going on?

And if the rule for p*q is δp/p + δq/q

how might you apply that to x5?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
