Can some one intergrate 2*((r^
Can some one intergrate 2*((r^
(OP)
Can some one intergrate
2*((r^2-x^2)^0.5)dr from (r-c) to r
where r is defined as 7
but c is undefined
thus you get an expression for 'c' that I can substitute
into another equation and then solve for 'c'
This should be the small area of a circle divide my a chord length
Thanks

RE: Can some one intergrate 2*((r^
It does not make sense in my opinion - what is x? why does r appear in the limits, and in the formula, and as the integrating variable?
However on the assumption you are correct
the indefinite integral comes to
r*sqrt(r^2-x^2)-x^2*ln(r+sqrt(r^2-x^2))+A
where A is a constant
But as I said, probably meaningless

RE: Can some one intergrate 2*((r^
integral(a,b, sqrt(R^2 - x^2),dx)
then MathCAD can symbollically
evaluate this integral. Also note
that the limits are:
a = C (Not R - C),
and
b = R (radius of the circle)
Incidentally, C <= R.
You may want to consider changing the lower
limit to C a percentage of radius !!
Take care,

RE: Can some one intergrate 2*((r^
(r-c)*((r-c)^2-x^2)^0.5
-x^2*ln(r-c+((-x+r-c)*(r-c+x))^0.5)
- r*(r^2-x^2)^0.5
+x^2*ln(r+((-x+r)*(r+x))^0.5)
Hope this helps
