Help needed with a simple question.Hi everyone. As i said in my intro I am a welder. I've been asked to construct a spiral made up of triangles. Like most jobs I have sat down to draw it out and make cutting lists etc so I can give the customer a fair estimate of cost. #2 20130811 02:27:42
Re: Help needed with a simple question.
Is a and A the same? Is b and B the same? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130811 02:39:26
Re: Help needed with a simple question.If A + B = C In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20130811 02:41:57
Re: Help needed with a simple question.To clarify, I know the statement #6 20130811 02:50:31

Re: Help needed with a simple question.
A quick look around suggests I need to be looking into recursive,would that be right? thanks for your help, much appreciated Last edited by bill.stead (20130811 02:52:41) #8 20130811 03:01:11
Re: Help needed with a simple question.That is where I was trying to take you. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20130811 03:27:25
Re: Help needed with a simple question.ok, if we start with an equal triangle number 1 with short sides 2m. Then the long side is 2.8m. That then becomes one of triangle number 2's short sides.so triangle number 2s long side is 4m. that then becomes a side for triangle number 3, etc etc.that creates a spiral made of triangles that increase in size in relation to the previous triangle. (I've rounded the math up a bit). #10 20130811 03:34:10
Re: Help needed with a simple question.Hi;
How does that happen? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #12 20130811 03:52:03
Re: Help needed with a simple question.That is what I mean T3 is impossible. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #14 20130811 05:11:42
Re: Help needed with a simple question.How can the sides violate the triangle inequality? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #15 20130811 05:18:05
Re: Help needed with a simple question.Sorry. My mistake. When I'm 'on the case', my maths jumps ahead so fast, my arithmetic cannot keep up. You will have seen me do this sort of thing many times.

Re: Help needed with a simple question.Would it help if I put up a quick drawing to explain what prompted the question? #18 20130811 06:46:59
Re: Help needed with a simple question.This is the drawing for half of a window frame to be welded up. #19 20130811 06:53:33
Re: Help needed with a simple question.As you can see from the above drawing, each triangle is extrapolated from the one below. #22 20130811 07:30:05
Re: Help needed with a simple question.Thank you both very much for your patience . I can see I have a long road ahead of me to understand all of that. At least I know what to look for now.
