    Trig Function Question

    It's been years since I've worked any trig, and I was working an algebraic equation determining a distance between 2 points when the vectors are on a 90 degree tangent to each other from a common origin point (2 people walking, one at 2 mph and one at 4 mph). If it were a trig question, I'd have a known hypotenuse of 3 miles, and unknown values for a and b, other than b=2a.


    I just plain can't remember beyond this point.

    so we know hyp., which is 3 and b=2a

    http://faculty.uoit.ca/kay/G10_AppWebPage/

    Pythagorean theorem says: c^2=(a^2)+(b^2)
    since b=2A and c=3, you can substitute it into the equation and write it as
    9=(a^2)+(2a^2)
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    AAAAH, Thanks! I knew I was on the right track.

    So, then a=SQRT3 and b=2(SQRT3), then. I ignored the negative result since I was using it for distance in the real world, by the way.

    Two parts couch, one part match. Sorry Tom, I killed my Trig brain cells years ago.

    Tom, you didn't quite get there:=

    9=a^2+(2a)^2
    9=a^2+4a^2
    9=5a^2
    9/5=a^2
    SQRT(9/5)=a

    Enjoy
