Mathcad can be fun

    Mathcad can be fun banner

    Albert Einstein was definitely onto something when he said, “Creativity is intelligence having fun”. We have some proof that Mathcad can be fun and still productive. Try solving a Mathcad puzzle, and see if you can get the result and brag about it to your colleagues and fellow professionals.

    Follow the instructions below:

    • Use READPRN to read the file xmas.prn into a variable v
    • Create a 3D plot (Ctrl 3)
    • Add traces (Shift-Enter) until you’ve got 15 input boxes
    • Enter v[0, v[1, and so on until v[14 into the placeholders
    • Click on all the fifteen inputs one after the other and set the Format of the fifteen traces:
      • First: Surface Fill = tree green
      • Second: Trace Color = trunk brown, Trace Thinkness = the thickest
      • Third: Surface Fill = a nice ball colour, maybe red
      • Fourth: Surface Fill = another nice ball colour, maybe yellow
      • Fifth: Surface Fill = yet another nice ball colour, maybe blue
      • Sixth: Surface Fill = nice box colour
      • Seventh: Trace Color = nice colour to go with the box above, Trace Thinkness = the second thickest
      • Eighth: Surface Fill = another nice box colour
      • Ninth: Trace Color = nice colour to go with the box above, Trace Thinkness = the second thickest
      • Tenth: Surface Fill = a floor colour
      • Eleventh: Surface Fill = a star colour
      • Twelfth: Surface Fill = wallpaper colour
      • Thirteenth: Trace Color = silver, Trace Thickness = the second thickest, Line Style = line
      • Fourteenth: Trace Color = gold, Symbol = Yes, Line Style = none, Trace Thinkness = the thickest
      • Fifteenth: Trace Color = nice mat colour
    • Set z-axis max to 10
    • Hide Tick Marks and Tick Mark Values for all axes
    • Hide Axis Expressions

    Congratulations if you’ve solved the puzzle!
