## What's under the hood?...

@acer Thank you for your help. I wonder why your sheet is working, and curious about what's happening under the hood? How to do faster (although your current solution is fast enough for me)

## make the float-point exponent a fraction...

@acer @Carl Love  thanks both. Just to confirm, so the essential idea is to make the float-point exponent a fraction?

Am I nitpicking or indeed this is a wired bug of Maple?

## Great Thanks!...

@acer And the ``Digit'' was a typo that I should find out before I post this question. But thanks for your reply that is very sufficent

## Thanks, but what is the difference behin...

@Kitonum Thanks, but what is the difference behind the two ways..

## purely numeric integration VS symbolic i...

Thanks.

Sorry for being slow, could you please explain more on ``purely numeric integration VS symbolic integration''? is it simply use the int(blah, x=0..1, numeric=true)?

## @acer    ...

Define the 3 profiles:

 (3)

 (4)

 (5)

 (6)

 (7)

 (8)

Now set g(x) which is a beta distribution with the two parameter a, b as:

 (9)

 (10)

 (11)

 (12)

 (13)

 (14)

Now define the 3 factors: 1. the oj/tj=max(oi/ti) 2. tl=min(ti) 3 Andrey's K

 (17)

Then slove the equition

Here you are.. Change the Digits at the begining and rerun the whole sheet you will see different results.. Thx

## Thanks!...

No matter how stupid and simple my question is, I can always find clever tricks/answears in this community!

## Thanks it works but why......

@vv Thanks it works but why...

## @vv Sorry, no actually. 20 minutes passe...

@vv Sorry, no actually. 20 minutes passed and it is still evaluating...

## @vv thanks, I made a mistake, it should ...

@vv thanks, I made a mistake, it should be evalf(Int(z*PDF(0.3*p1+0.7*p2, z, inert), z = 0 .. 1));

## Sorry, are we talking about the same pro...

@Thomas Richard You see the plot is in the style of @"pointline", but in the legend it is "line"...

## Not really, since black-white print.....

What if I prefer my paper printed in black-white style...

linestyle is still not pretty in the case of there is horizontal line ( which will overlap with the gridlines... )

## @acer Yes, sorry for being misleading....

@acer Yes, sorry for being misleading.

## @Rouben Rostamian  But I got a erro...

@Rouben Rostamian  But I got a error:

Error, (in fsolve) yval is in the equation, and is not solved for

## @Rouben Rostamian  Thanks. But I do...

@Rouben Rostamian  Thanks. But I do not know the colse form of f(x,y), rather there is a fsovle(x,y) in the expression of f(x,y).
