Maths Course

mikee55 · 7th October 2006, 02:29 PM

Hello Everyone,
This might be UK related, my maths is very limited,ie I can Add, Subtract, Multiply and Divide. Can anyone suggest a course for studying math in the South UK? I would like to be able to calculate things related to Loudspeakers and Electronics (Volume and Mass through to crossovers). Formulas look foreign to me, likewise Algebra. Something like a Learn Direct course would be good. At school, I didn't want to know because I just couldn't grasp what was being said or even examples I was shown and my maths teachers would get frustrated and I'd get nowhere.Now I'm 35 years of age, and still struggling.I bought a couple of books years ago. I've got the Eminance PA Cabinet book and the Kappellmeister book and even in these, the math is beyond me.
Can you suggest something to get me on the right path?Full time College is not possible. I did try a course, an Electronics Diploma, but it was too intense.After 3 weeks of Algebra the Tutor wanted to go on to Trigonometry

So I had to quit.
An On-line course would be okay but I'd prefer someone to be there if I can't grasp somthing.
So please help.

Thankyou Mikee55

I struggled with maths just before my GCSE years, then my parents got me a maths tutor who taught me an hour every Tuedsay night for a year or so. He was a good teacher I'll admit and I think I was lucky to find a teacher like that, but I could get 100% consistently in past papers after he had been teaching me a while.

So if you can afford it maybe a maths tutor would be a good investment. I think it was about £7 an hour back then, lol just realised it's about 15 years ago.

Have you tried any sort of workbooks (that's what they call them in the US)? THese are usually inexpensive thin magazine-sized books (often printed on very cheap pulp paper) which are kind of a course in a book with lots of fully worked out examples.

From the sounds of it, you may be more intimidated than lacking in skill. Math really isn't insurmountablly hard, some people just have a mental block that it is harder than it actually is. If you can think logically (and your sentences seem to imply that) you can do math.

Take a look through a local library or book shop, spend some time actually paging through some books and see if you find any that have an approach you like. Sometimes the applied math type books have examples that illustrate concepts better.

Most importantly, stick with it, and have fun.

Hi, is this book any good for the electronic side of things?

Electronics for Dummies

Ron E · 8th October 2006, 02:56 PM

I have never seen a "Dummies" book that was worth anything on technical topics. I would expect that book to be more about defining terms in laymans language than teaching you to calculate anything, but I could be wrong.

What do you want to calculate?

If you couldn't do maths as a child you will struggle just as much if not more as an adult even if you are now prepared to hang in there and make the effort. If you can do maths then online courses and books can be a useful way to extend the knowledge but they are not particularly useful if you are baffled by maths in which case you really need a human teacher to help work out what is baffling you and help fix it.

Evening classes at the local school/tech can be effective if you sort out your project beforehand and rope the teacher into your project and your examples at every opportunity. Chatting with fellow strugglers in the pub afterwards can also help in not giving up too easily.

Hi,generally looking to be able to calc everything to be able to take a bass driver and tweeter,check its T/S parameters and constructing a box for the driver.Then calculating xovers etc for drivers. Also everything associated with Linkwitz Transform for subwoofer design. I've read the ESP article and am struggling with volume taken up by magnet etc.

Cheers mikee55
