comment Find area bounded by distance from a curve
@DavidK isn't there a separate issue where the curve is Florence flask shaped along the neck (if its narrower than $d$)

comment Find area bounded by distance from a curve
@NominalAnimal, Those would be helpful. If it matters, my curves self intersect a small number of times ( < 5) and accuracy does not need to be so precise.

@DavidK Do you see an approach that is not counting pixels?

comment Find area bounded by distance from a curve
That's what I'm doing now, but its rather slow. I was surprised to see that such a simple to state problem doesn't have an easy analytic solution. Could I get a tighter bound by calculating the curves curvature at all points?

Would left minus right as defined here math.stackexchange.com/questions/167543/… work?

But is there a way to get an actual value?

@mvw that is it exactly. I'll reword it to make it clearer

comment Find area bounded by distance from a curve
if the curve is a straight line of length $l$, then the area would be a rectangle of length $l$ and a height of $2d$, and then two half circles on the ends (with radius $d$)

comment Find area bounded by distance from a curve
@mvw d is just a constant, so I want "the area within distance d of a curve"

comment Finding the volume between a cone and a sphere
@user_of_math That question is very much related, but I have no idea what is supposed to go inside the integral for example, and the answer and question don't help me out there

@Glen_b, I figured it out, but thanks

comment Generate Sequence with given variance and mean
@Glen_b the generated sequence can be any distribution. I hear your point about the 0's, but I'm sure what else to look for. The mean and variance are for the sequence

@AndréNicolas Is the question underspecified, or can I just pick a distribution, defend it, and thats it?

The worst example I've ever seen is "Ours is not to reason why, ours is to invert and multiply" oh the irony.
