There is a tree growing in my yard which yields some type of citrus fruit and I'm not exactly sure which type it is. The tree itself is about 6ft tall and has green thorns which are between 1.5" to over 3" long. The leaves are small and there seems to be as many thorns as leaves. It currently has yellow fruit on it which is yellow and appears very similar to a lemon, however, the fruit is perfectly round though sometimes a bit ruddy, and they never get larger than a golf ball. There is no lemon "nipple" to speak of and there is light fuzz covering the rind which doesn't appear to be mold or fungus and is similar to peach fuzz. When cut open the fruit is distinctly citrus and gives off a smell which is similar to a lemon but has a bitter "don't eat me" scent to it. Instead of falling off the tree and decaying, these things turn brown and rough on the tree and fall off as dry, hard pod like things.

I'm stumped, any ideas on what it might be?

let to borrow has used a superglue to glue the string on to the hole, so what can I do to take that string off? Is there some chemical products I can use to dissolve the glue?

I am trying to evaluate the Bromwich integral which computes the inverse Laplace transform of a given function. The integral is as follows:

/c+i*infinity
|
I F(s)*exp(s*t) dt
|
/ c-i*infinity

where F(s)= s^p/(s^2+1)^q
p and q are positive, c is greater than the real part of all the singularities of F(s), and i^2=-1.

So the integration is done along the vertical line x=c in the complex plane.

I appreciate all answers or hints. If you can't work with F(s), substitute values for p and q and work with that.
