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 :)

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?

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.
