while I agree with the conclusion, the math is wrong, you only need three for a curved line, a sthraith line can easily be made with just twoKenaz said:But for a straight line you need three...Fox said:That's all you need to draw a line!josiah42 said:I wonder if there's a pattern here.

More touchy-feely is clearly needed!
For science.
True, but a straight line with two points can still be subject to experimental uncertainty. What is it's just the first two points of a scatterplot? With a third point we can verify on a graph that a true data line exists.vegetalss4 said:while I agree with the conclusion, the math is wrong, you only need three for a curved line, a sthraith line can easily be made with just two
