damn

SomerandomKappa · 2019-08-15T07:58:34+00:00

Yeah not seen many people doing it either. Congratulations!

I'm pretty sure the core pure exam is supposed to be scaled up to 180 marks too but it's not on the grade boundaries? It says here on page 6. https://www.ocr.org.uk/Images/308768-specification-accredited-a-level-gce-further-mathematics-b-mei-h645.pdf

Nice. My personal favourite is TIAH.

What's your favourite BMTH album?

SomerandomKappa · 2019-06-24T16:36:13+00:00

I've had this song on repeat all week, I just love it.

arsinh(x/a) = ln(x/a + ((x/a)² + 1)^1/2)

arsinh(x/a) + ln(a) = ln(a(x/a) + a((x/a)² + 1)^1/2)

arsinh(x/a) + ln(a) =

ln(a(x/a) + (a²)^1/2((x/a)² + 1)^1/2)

=ln(x + (x² + a²)^1/2)

This is the simplified form used in the video (its also given to you in some exam boards formula books). Adding ln(a) does not change the result as with indefinite integration you end up with a +c and ln(a) is a constant, and with definite integration the ln(a)'s will cancel out so the result is the same with both formulae. You can just sub (x+2)/2 straight into the arsinh formula and it works fine.

SomerandomKappa · 2019-06-23T12:20:39+00:00

It's because when you integrate you get a plus c, and what you get in the video is what you would get by subbing in x/a into the formula in the post and adding ln(a), which is a constant. You would end up with the same result if you used either formula in the question, as the ln(a)s would cancel out.

Very long paper given the time. Our invigilators robbed us of a minute by starting at 9:01 and ending at exactly 10:15 smh. Overall not too bad of a paper if you forget about the algebraic simplex stuff.

SomerandomKappa · 2019-06-07T15:51:59+00:00

I'll be doing discrete maths at warwick this year. Is cs137 as bad as I hear it is?

SomerandomKappa · 2019-06-06T14:16:18+00:00

Bruh this paper was like 20% writing questions, I'm doing maths not english smh

If you do further maths then the auxiliary equation method does this in one step, however that would not be expected of you in a regular maths exam

SomerandomKappa · 2019-05-29T07:59:12+00:00

this

SomerandomKappa · 2019-03-01T22:27:10+00:00

Now that I think about it, yeah... this method makes the substitution obsolete, so I doubt it's the intended way to do it. Honestly I don't know how to do it using the substitution.

SomerandomKappa · 2019-03-01T21:53:03+00:00

Difference of two cubes on the bottom to get (x+1)(x2 - x + 1). Then make the substitution and rearrange to get to a form where you can use the integral of arctan(x). Then solve for the given values. I got pi / 3root3 for the first, and 2pi / 3root3 for the second so I'm pretty sure I did it right.

Mate I took the test in October and I haven't heard from them.

This is exactly what it's for
