    I don't understand any of the above, but I've just made another couple of pcbs.

      Which I'm now going to drill some holes in.

        I should really periodically move them onto my NAS, but can't be bothered.
        Mine did but recently the extra 50Gb that Dropbox provided me with for free ran out so I stopped using it altho it does automatically transfer to the NAS via a service running on it, I just need to clear it out tbh.

            I have 7.8GB of Dropbox available, and cleared a load of stuff out recently which shouldn't have been there.

            I have more space than I realised now - I think it could have been photos that I removed from DropBox, though

              That's more than anybody else here has managed in a long time

                Possibly.

                Though there's no hammer action so the whole building doesn't resonate properly.

                For maximum effect you need to drill one of the columns & get all the girders vibrating.

                  You just have to take logs of both sides.

                  And try to remember how you convert Log base 3 to ln or log10.

                  After which, it's a breeze.



                  The other way is iterative use of calculator.

                  That was worth 3.5 marks by the way.

                  The lines you're missing are

                  3^x = 45
                  x = ln(45) / ln(3)
                  x = 3.806 / 1.098
                  x = 3.465

                  Next is to try and remember how to multiply matrices

                    I'd wager you're correct, young feller me lad.

                      Next is to try and remember how to multiply matrices
                      or solve 2 ln(x-40 = ln(x-3) + ln(x+9)

                      Also worth 3.5 marks.
