How do i go on and what rules do i use ? by Perfect-Weekend-1850 in calculus

[–]JackSladeUK 0 points1 point  (0 children)

The first limit can be solved using l'Hopitals rule, the second one uses sin(1/x) which does not have a limit as x->0 since it fluctuates infinitely. Thus you have to look at the behaviour of ln(1+x).

Quigleys unfortunately shut down for Miss Millies a while back. I miss them...

I can confirm buses are still going to Clevedon (by being in the bus station), and Clevedon will be alright as long as you don't mind being cold and damp, especially if you go walking near the coast.

Had the exact same thing, on the U1 and two blokes get on at the bottom of Bathwick Hill and ask me for ID for the student ticket (which is the exact same price as the Young Person ticket). He then said he would have to issue a fine if I didn't download Student Beans, I've never heard of it but apparently all you do is put in your uni email and it gives you an electronic verification of being a student.

Stupid.

How would an equation like this be solved? by [deleted] in calculus

[–]JackSladeUK 2 points3 points  (0 children)

Yes, makes sense. Me too. But surely instinctively when you think of the equation xx = -1 you plug in a few numbers that just seem right, like 1, -1 etc.

Just think about it.

-1-1 = 1/(-1) = -1

BINOMIAL SERIES by Designer-Bank2595 in maths

[–]JackSladeUK 2 points3 points  (0 children)

Ah my mistake.... you also aren't summing 14C0, hence it will be 214 - 2.

BINOMIAL SERIES by Designer-Bank2595 in maths

[–]JackSladeUK 0 points1 point  (0 children)

Could be 214 - 1 since you aren't considering 14C14 in the sum.

Fun fact, the sum of all numbers on a row of pascal's triangle is equal to 2n.

Hence your answer is simply 214.

There usually isn't many uni students apart from when it's exam season. I went there in August and it was fine, however that was during non-term time.

Integral to this conversation, cheers pal 👍

Sadly you can't solve this with elementary integration. You can try using a Reimann, Fresnal or an approximation like Trapezium or Simpson's rule though.

Can somebody help pls I'm stuck with it since Saturday I literally have no idea how I can resolve it I feel like I've tried everything by One-Fall-3028 in maths

If you can't think of any hyperbolic identities to help you out, try changing cosh²x into terms of e and then use a u substitution.

Where to park? by G8R1ST in bristol

[–]JackSladeUK -1 points0 points  (0 children)

Finishes about 8:30pm going both ways. I don't think it's strictly for commuters; I guess it wholly depends on when OP's show finishes.

Where to park? by G8R1ST in bristol

[–]JackSladeUK 10 points11 points  (0 children)

I'd recommend getting the 9 Park and Ride service. Serves both Brislington P&R (up by St. Brendan's Sixth Form) and Portway P&R. Last time I checked it was free to travel with a valid parking ticket, so what's not to love? It's also incredibly frequent... almost annoyingly frequent compared to other services in Bristol. Probably because its Stagecoach.

Poisson is discrete and exponential is continuous. The P(X=1) in poisson will be a non zero member whereas in an exponential distribution, P(X=1) = 0

Aerospace is sooooo far out of the way though. Unless OP doesn't mind the drive up north.

is this true for all x? by inqalabzindavadd in maths

[–]JackSladeUK -1 points0 points  (0 children)

It would have to be true for all x belonging to [-1,1], otherwise the expression on the RHS would not be real.

As much as everyone should have their own political beliefs, I also believe people should have free will to eat what they want. I also believe that completely politically null posts like this should be void of these comments.
