b = -5

5a – 3(-5) = 25
5a = 10
a = 2

Of course! 😮

Oww…brain ache. Spent 2 hours in Maths today…Intergration and Differentiation. Ugh…Along with Quantum Physics in the middle of the day 🙁

Follow that? All the other 3 follow roughly the same method. See if you can work some out….I’ve only just got home from my A-Level maths class!

1.
5a – 3b = 25
3a + 3b = -9

multiply each equation to make ‘a’ equal:

15a – 9b = 75
15a + 15b = -45

Subtract the 2 equations, 15a is eliminated. Left with:

-24b = 120
24b = -120
b = 5

Sub b back into original equation to find a:

5a – 3(5) = 25
5a = 40
a = 8

Therefore, answers are : b = 5, a = 8

Nice work Paul!

Just having a look at the EXIF data on those shots, it seems that you are using an aperture of F2.8. This will make it very hard to get a sharp front-to-back shot. I would usually aim for atleast F7.1, preferably F9-11. Obviously the narrower your aperture
(the bigger the number, the narrower), the slower your shutter speed. This means you’ll have to try extra-hard to keep the camera still, otherwise it’ll blur.

If the weather really is appauling, I’d rather try and keep an aperture in the region of F8,and bump the ISO to 200 or in desperate cases, 400.

7. Oasis – What’s the Story Morning Glory

9. The Verve – Urban Hymns

One of the most powerful albums I could ever listen to…just something about it.

And Dan, yes they were sparks

Is that expected/normal?

Great stuff Elgan, looks like a good week.

AB STN-MAN-STN is scheduled as 734. Yet I managed to get a couple of Fookers, and you got the Dreamliner!
