The "Request" instruction allows to have a dialog for just one input, but if I would like to have two inputs to me it seems impossible.

I'm wondering if there is any solution for this

]]>My program is suvat as in make your choice s,u,v,a,t.

I need three letters from suvat to solve a problem.

nCR(5,3) gives 10 combinations I assign to numbers 1-10.

num=seq(x,x,1,n),n

Request ("what is your number?"),n

if num[n]=n then

goto block

Every time I want to solve a problem I need to look up the block number to use.

My question: is there another way to do this kind of thing?

I'm trying to learn how to use this calculator.

Anyone that can help me write some programs? The first one needs to be a program that shows the prime numbers between two parameter (a,b).

Got 3 more programs to write after.

Can pay (small) if someone wants to do it for me

Here is the HP Prime Code that works

n-Erlang distribution (see also Gamma and exponential)

Code:

EXPORT erlang(k,l,n)

// n-Erlang distribution k shape parameter, l=λ >=0 rate parameter

// from Gamma d.; if k=1 -> erlang(1,l,n) = exponential(l,n)

// erlang(k,λ) = gamma(k,1/λ)

BEGIN

local f;

f:=piecewise(n<0,0, l<0, 0, ((l^k)*(n^(k-1)*e^(-l*n)))/(k-1)! );

END;

EXPORT erlang2(k, m, n)

*k shape parameter, m=μ=1/λ >=0 scale parameter* if μ=2 -> chi2 with 2k degree of freedom

BEGIN

local f;

f:=piecewise(n<0,0, m<0, 0, (n^(k-1)*e^(-n/m))/((m^k)*(k-1)!));

END;

EXPORT erlang_cdf(k, l, n)

// k shape parameter, l=λ >=0 rate parameter (μ=1/λ)

BEGIN

local f;

f:= 1- sum((1/X!)*(e^(-l*n))*(l*n)^X,X,0,k-1);

END;

And this is what I tried to do for one of them for the Nspire but I am getting an Argument Error

Define erlang(k,l,n)=

Prgm

local f

f:=piecewise(n<0,0, l<0, 0, ((l^k)*(n^(k-1)*e^(-l*n)))/(k-1)! )

EndPrgm

It seems to look correct and is able to have a "Stored Success" but I feel like I'm doing something wrong. I would really like some help here.

in my TI-Nspire CX So far I have the following code but am getting variable not defined in if statement.

Here is the code I have in my Nspire CX so far.

`Define LibPub modinv(a,b)= Func Local b0,t,q,x0,x1 0→x0 1→x1 If b=1 Then Return 1 EndIf While a>1 q:=((a)/(b)) t:=b b:=mod(a,b) a:=t t:=x0 x0:=x1-q*x0 x1:=t EndWhile If x1<0 Then x1:=x1+b0 EndIf Return x1 EndFunc`

the inspire is throwing an error on this line.

` If x1<0 Then x1:=x1+b0 EndIf`

Not sure what I am doing wrong here! Any insight would be appreciated!

How do I make any phrase/word be able to be said on any “say something”? Because I just says say something I type r and it says say something again and then I say r and it works. I want to not make it an orderly fashion and make it work every time… please help me… ]]>

`Disp “score=“,score”%”`

So the output is:

`Score=80%`
