Definite Integrals

  1. Jun 24, 2007 #1
    ok so what has happened is my friends website is moving to a new location,
    he said the only way i can get to see it early is if i get the answer to this, he did this because he knows i know nothing about math.... so im one of you guys or gals can help me...

    THE AREA OF A SQUARE WITH SIDE LENGTHS EQUAL TO THE

    DEFINITE INTEGRAL OF (0.43890022*X) FROM 1 TO 10

    thank you all
    Merven

    p.s. i hope i put this in the right section lol i was told integrals are calculus :)

    no i just finished HS with only minimum math so im tottaly in the dark....

    Right, so it would be pointless to show you how to obtain the answer, because you don't know how to do it! You just want the answer! Have you even given it a go?

    thanks

    well, assuming that u dont know the definiton of the definite integral than here we go. The definite integral of a function is given with this formula:
    integ f(x)dx, from a to b = f(b)-f(a)
    Actually this is the area that the curve given by the function f(x) closes with the Ox axes.
    So, also you need to know that integ k*f(x)=k*integ f(x), where k is any real constant. Also you need to know that integ x dx = (x^2)/2

    I think this information is all you need to do find one of the axes of the square, and consequently the whole area of the square.

    I hope i was helpful.
