i think your right, the coordinates switch but the negative remains on the left hand side of the pair. for example if you had a set of axes -8 to 8 and you had a point at (-4,2) then if it was reflected on the line y=-x it would become (-2,4). well she can if it s not right
I’m useless at mathematics but it seems to me that any co-ordinates (two or more) that appear in a reflection or shadow have the original properties x,y inverted, (x,y)-z where z is the mirror image (minus or negative) plus another variable lets say (dv) to account for distortions introduced by the method of reflection in relation to the original. Plus another variable for all the distortions introduced from your viewing point back to the original (dz). This can include angular for say shadows (az), which are a sort of reflection, or logarithmic for size distortions (lz), or momentum for time distortions (tz) and I suspect that the mathematical formula which must be expressed as three objects where two must be known so as to calculate this from any perspective is horrendously complicated.
Attempting the same through a perfect mirror or substance with only one reflection does not produce any worthwhile answers.
Now you know why I’m useless at maths, I only understand the logic of a dartboard as viewed through a reflection in the bar overhead mirror.
It’s no good looking up the answer here, you must have an understanding of how to approach the problem and hence work out the answer yourself even if it’s wrong.
What will happen if you can’t locate the solution on the web? You will have to start thinking in the wild. This will give you the logical path to follow to answer any problem thrown at you in mathematical terms. Maths in simple it’s only adding and subtracting everything else is expressed as shorthand code (like logarithms) for a quick solution.
1 & 1 still equals 11. Nothing plus One plus one = 2
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
