x axis at our desired number of points

I have:

tmax = 1.2*0.1*10^11; Plot[t^5, {t, 0, tmax}] 

dd Then I get a picture as above. This is pretty easy data and the width of two points in x axis won’t affect the clarity of the figure. I used this example to let you know my requirement. In MATLAB, we have an option to set the width of the x axis. Look at the second line of the below code in MATLAB.

tmax=1.2*0.1*10^11; tt=0:0.1/100*10^11:1.2*0.1*10^11; 

How to select the plot width as 0.1/100*10^11 in mathematica as easy as in MATLAB. I have asked a similar question earlier and the suggestion I got is really difficult and I didn’t really understand. Is there any easy way? I have searched the documentations and can’t come up with any!

Excluding points from 2d plot

I am trying to plot certain regions using ContourPlot and RegionPlot in two dimensions. From these implicitly defined contours I need to exclude certain points. In the documentation of Exclusions it says that for a domain defined by $ n$ variables, exclusions must be of dimension $ n-1$ . Since points are dimension 0 objects, it does not work to exclude them naively. My idea to circumvent this issue was to include short line segments through the points and exclude the lines instead, which would not be a problem with my plot. However, I do not find anywhere how this can be done. An example for a plot can be found in this question. Any help is much appreciated.

Numerical value of Derivative of Dirichlet L function at some particular points

I want to find the numerical value for the derivative of Dirichlet L function to compare with an another formula. However I am not able to obtain any numerical values. I tried to use

f[s_]= DirichletL[5,2,s] f'[3] 

But this simply returns DirichletL^(0,0,1)[5,2,3]. If I use N[f'[3]] this gives: DirichletL:: Positive integer expected at position 1 in DirichletL[5.,2.,2.].

Can someone please help me out with this? Any help is highly appreciated.

SQL30080N error points to two documents SC31-6160 and (SC31-6156

If I face this problem: SQL1476N with sqlerror "-30080", then I check this other error:

db2 ? sql30080   SQL30080N  A communication error "<reason-code>" occurred sending or       receiving data from the remote database. ... Refer to the document IBM Communications Manager 1.0 APPC Programming Guide and Reference (SC31-6160) for explanation of the APPC primary and secondary return codes. For details of APPC sense data, refer to the IBM Communications Manager 1.0 Problem Determination Guide (SC31-6156). 

When can I get information about these documents?

How to recover void points

I am playing a game of the newest version of legend of the five rings, and cannot find in the book how can you recover void points.

In older editions it usually required a meditation roll or a tea ceremony roll (which now is a level 2 Shuji) or just plain rest.

Or are you supposed to not recover it as usually any more?

Can Lay on Hands be used to both heal hit points and remove diseases/poisons with the same action?

The Paladin’s Lay on Hands feature says:

As an action, you can touch a creature and […] restore a number of hit points to that creature.

It also goes on to say:

Alternatively, you can expend 5 hit points from your pool of healing to cure the target of one disease or neutralize one poison affecting it. You can cure multiple diseases and neutralize multiple poisons with a single use of Lay on Hands […]

Could I opt to do both at the same time? Perhaps an ally was struck by a crossbow bolt with drow poison, and I needed to both heal them as well as remove the poison in one go; is that permissible?

As written, it seems vague. The first paragraph specifies the use of an action to heal hit points, but the second simply indicates an alternative way for the hit point pool to be expended, but doesn’t seem to indicate that the use is exclusive from the first.

How much damage is dealt/taken when that damage also reduces a creature to 0 hit points?

The particular case where this question came up was when a Hobgoblin Warlord attacked my ally, who had 7 hit points remaining. The attack’s damage was rolled for a total of 13, meaning they would fall unconscious. However, I am a Redemption Paladin which means I can Rebuke the Violent:

[…] Immediately after an attacker within 30 feet of you deals damage with an attack against a creature other than you, you can use your reaction to force the attacker to make a Wisdom saving throw. On a failed save, the attacker takes radiant damage equal to the damage it just dealt. […]

The question that arose was how to calculate "the damage it just dealt". Did the Hobgoblin Warlord deal 7 or 13 damage to my ally?

The only thing I found that somewhat answered this was the section on "Instant Death" which includes the following (emphasis mine):

[…] For example, a cleric with a maximum of 12 hit points currently has 6 hit points. If she takes 18 damage from an attack, she is reduced to 0 hit points, but 12 damage remains. Because the remaining damage equals her hit point maximum, the cleric dies.

This seems to state that the Cleric still takes 18 damage, even if her points drop to 0, but then it also states that 12 damage "remains". It’s not what I would call definitive and it doesn’t explicitly state that that is how damage works so I’m wondering if there’s anything that makes this even clearer.

How many hit points does a bedroll have?

The PCs are battling a bat swarm, and lit a bedroll on fire and are trying to chase the swarm away by floating the burning bedroll at the swarm with mage hand.

The bedroll will take 1d6 fire damage each turn, but I can’t find how many hitpoints a bedroll would have (in this case, sized for a halfling). Let’s assume the bedroll is still rolled up, and not spread out.

Rope/cloth has 2 hp per inch of thickness: I guess it’s kind of a GM call?

Edit: a simple google search gives this choice as one of it’s first results. It has a long and short option. If we take the rolled width of the short bedroll (for a halfling), it’s width is 8 inches. At 2 hp/inch, that gives it 16 hp total. That sounds reasonable enough, I suppose. Depending on the fire damage rolls, that’s at least 3 rounds.
