    Its part of a formula for calculating the DPN for a sailboat. For racing. its used for multiple class races to even out

    1.3 * sqrt(160 is what google will accept as the equation)

    OK......thanks! but I think that is wrong...... Will someone with a good old fashioned HP Reverse polish notaion calculator check this for me. I think it is actualy: 1.3rd root of 160 = 49.5994556 1.3 * sqrt(160) = 16.4438438 is really saying 1.3 times the square root of 160 which is like 12.65, so 12.65 x 1.3 = 16.44 OK so after 30 yrs I may not remember everything I learned in HS, but I do know enough to check alternate sources, and I do have common sense. Thanks for the help!

    OK I guess no one on here right now prob even knows what I'm talking about when I say an HP Reverse polish notaion eh? Well its simple a term we used in the 90's for the Hewlet Packard high end calclators where you input in rverse of standard calculators.

    you think its 1.3 as the root to the radical instead of a square root?

    1' 3/10 = 13/10.. 160^(10/13) is the answer to that one then

    they have formulas but not much detail on how to use them. I was a Mech Design Major so I only use math whem I have to..LOL and my old collge Calc died 2 yrs ago...guess I should go buy a new one.

    lol no...it was a K-mart special...but a decent brand name..don't remember exactly..something like texas instruments or equiv. Couldn't afford an HP @ $300 while working way thru college. but it worked good enough to get me by with decent grades

    It even had most of the mid to high level Statistics functions so it saved my butt in Statistics..it came with a little instruction booklet on how to use it and it was very detailed on how the formulas worked...like a little cheat sheet....got A's in Stats cause of it.

    You'll have fun in Statistics..not as boring or hard as some make it look. Just remember...no matter how many times you flip a coin and it comes up heads, the odds it will be heads on the next flip is stil 50%....Statistics Trick ??? some instructors like to use.
