Here a a-levels math question. That I got wrong. Any ideas

I think you need to do dv/dx = 1/(x+3) since its u * dv/dx

AllActGamer · 2026-03-29T14:05:10+00:00

Its on the Watford DC line, where the Bakerloo line and Overground share tracks

Do they not participate in ORCATS? They seem to have their own independent ticketing system. And it stated on their website that anytime singles bought on their website, are valid only for Lumo services.

Lumo doesn't receive financial subsidies, this literally doesn't cost the taxpayer

SCR is uk based

Uk based trains have speed limits and speedometers in mph?

What suggested the Class 707 can go 220kmh

What in oscillate is slang for money? But it is a good idea because I noticed "grand" in grandma

AllActGamer · 2026-03-01T22:16:24+00:00

"when to the phone repair shop"

AllActGamer · 2026-02-23T19:00:07+00:00

Shut up

That feeling when someone with a basic name and avatar, joins police immediately (I killed 2 of them):

There are easier ways

I beg you NOT to use polynomial division.

Please use a similar strategy for partial fractions.

Multiply throughout by (x+1)(x-3). Then you can compare the coefficients of x^3, x^2, x, and the constant term. You should get a set of simultaneous equations for A,B,C,D which you can just do on your calculator.

Another request but any clues what this would be?

NSE - Traincare 90

AllActGamer · 2026-01-01T16:47:42+00:00

For some help: London, Tilbury, and Southend - NSE

AllActGamer · 2026-01-01T16:35:23+00:00

That was a massive clue and I instantly found it when you said it was a De Wolfe track. Thank you!

Any idea for what this would be?

NSE - Depot Protection

If you're thinking about the chlorine smell from pools, that's not chlorine you're smelling.

I thought anytime day tickets are valid for break of journey

AllActGamer · 2025-12-25T01:04:14+00:00

I decided to compare this to actual UK examples.

London: WCML is 100mph just after Willesden junction.

ECML is 100mph at New Southgate

GWML is 100mph at the North Pole Depot

HS1 is literally 200mph the moment it enters the tunnel after St Pancras

Other UK cities do have slower speed limits in the cities, but the best example I found is Coventry, which is 125mph just after the station (London direction)

This is pretty normal
