Dick VK3ABK asked......
}
} Hello Calculators.
}
} Geoff, VK5KMG, sent a bulletin Titled 'Calculations' asking for help with a
} triangular problem.
}
} > Hi there, I want to work out the length of the hypotenuse of the triangle.
}
} I have seen one reply, from Andy, GM7HUD, (there must have been others!)
} and this would solve Geoff's problem. It may be of interest to know that
} this apparently simple theorem, named after Pythagorus, is not so simple.
}
} A mathematician, (which I am not) would demand proof that there is actually
} an answer to 'every' example of h^2 = b^2 + p^2. That is, does this apply
}
} to 'all' examples of three sides of a right angle triangle. We know from
} our limited experience that a 'correct' answer can be found and tested.
}
} But a mathematician will need 'a proof'!
}
And there is proof that every schoolboy learned when I went to school.
It was called "proving pythagorus from first principles"
If I remember correctly, it amounted to about 2 pages of calculations.
It was just one of the things that we had to learn to be successful at
GCE Maths.
But that was in the days when school exams actually meant something - unlike
today when even the dim-wits seem to come out with A* but still can't do
the simplest of things.
