How can I expand the time delay of neutrinos as a Taylor series?

AI Thread Summary
The discussion focuses on expanding the expression 1/(1-δ) as a Taylor series to determine the time delay of neutrinos. The user has derived a preliminary expression for the time delay but lacks experience with Taylor series. Assistance is requested to properly expand the expression using the necessary derivatives. The key steps involve calculating the derivatives of the function with respect to δ to facilitate the expansion. Understanding these concepts is crucial for accurately determining the time delay in the context of neutrino physics.

The Attempt at a Solution


I was able to express the time delay as D(1-\frac{1}{1-\delta}). However, I don't have a lot of experience using Taylor series and did not use one to obtain said answer for the time delay. Any help would be appreciated. Thanks.

They want you to expand the expression,

1 / (1-δ)

as a Taylor series. So you'll need the derivative of that expression with respect to δ.
 
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...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
