If Z is N(0,1) find

a) P(0<=Z<=.87)

I understand how to get to 0-0/1<=Z-0/1<=.87-0/1

which ends up being OI(.87), but am not sure how to get this to calculate. Plus I ant use proper functions here becuase I dont have the pallette, but OI is an O with the I through it... Φ(.87) I beleive....

I dont know how to have Maple calculate ths to give me the correct normal distribution value.

I have a Matrix 'A' in maple with symbolic entries and I need to use that Matrix in matlab M file. The symbols with in 'A' are already initialized in M file.

How is this possible?

For Matrices 'A' of small dimension, I can use the codegeneration package to convert 'A' to Matlab Matrix and then copy paste.

But for matrices of 1000x1000, lets say, does not seem as a option.

I was using maple as a documentation software and was preparing some notes for my exam. I had a sudden computer shutdown and the file didn't saved properly.

The file now opens but most of the content is gone. Even the one which was properly saved.

Hello,

I need to solve bond orders in Maple the formula is

Bond order = [number of bonding electrons – number of anti-bonding electrons]/2

I need to implement it in Maple, I dk how

Thanks

I was trying to solve for the equilibrium points for a system of differential equations.  Solving for the last equation, I encountered an error that I can't seem to find anywhere else.  "Error, (in Engine:-Dispatch) not implemented yet: 13". The code is below if anyone wants to take a go a figuring what's up.  Thanks!

Hi everyone, 

I'm new with maple and I have a big question. I tried really hard for 2 days to find the answer but... 

My problem it's really simple, i think...

this is the end of the program where is my problem:

      dsn1 := dsolve(dfin, numeric); 

      dsn1(1);

      proc(x_rkf45)  ...  end;

Hi! Today I tried Maple for the first time and unfortunately encountered a silly but really annoying problem. When I write a simple calculation expression like 2+2; it works as expected. However, when I use an expression like sin, ln, Pi, etc., the return (enter) key stops working, the program just doesn't accept them. I'm beginning to think this has something to do with my (quite old) Windows setup since I couldn't find a similar error anywhere in the internet.

I'm working on;

Q3) Write a procedure, isTriangle, to determine if any three given

 numbers represent the lengths of the sides of a triangle.
       The procedure should be able to deal with any input.

I have done the following and get an error

isTriangle:=proc(a,b,c::nonnegative and numeric)
if (a^2+b^2)=c^2 then print (a,b,c "represent the sides of a triangle")
end if;
end proc;
Error, unexpected string

Thanks very much for your help!

So I've done this so far:

Marks:=proc(m::nonnegative, numeric)
if m < 40 then print (m, Fail)
elif m < 50 then print (m, `Third Class`)
elif m < 60 then print (m, `Lower Second Class`)
elif m < 70 then print (m, `Upper Second Class`)
elif m < 100 then print (m, `First Class`)
elif m > 100 then print (`error`)
end if;
end proc;
proc(m::nonnegative, numeric)  ...  end;

Hello. I am trying to do a project. Howerver the following code is causing Windows 7(x64) to error.

First, I get a message from mserver.exe saying: mserver has stopped working.

I click "Close the program" and I get "Kernel connection has been lost."

This is happening when I calculate the Groebner Basis by the following code. It is all right when I calculate the Groebner Basis when the problem to be solved is simpler. The memory of my computer is...

Hi, 

When I try the example of a histogram plot from the help system (under Statistics, Histogram), I get an error.

The example (entered in document mode) and error follow below.  Can someone please shed light on this?

with Statistics; with(plots):
N := RandomVariable(Normal(0, 1)):
A := Sample(N, 1000):
P := DensityPlot(Normal(0, 1), color = "Niagara Red"):
Q := Histogram(A, averageshifted = 4, style = polygon, color = "LightSlateGrey"):

The system of ODEs i am trying to analyse is just a 3d model of a ball in motion with gravity and air resistence acting upon it.

restart;

with(plots):

eq1 := diff(x(t), t, t) = -k*sqrt((diff(x(t), t))^2+(diff(y(t), t))^2+(diff(z(t), t))^2)^(n-1)*(diff(x(t), t))

eq2 := diff(y(t), t, t) = k*sqrt((diff(x(t), t))^2+(diff(y(t), t))^2+(diff(z(t), t))^2)^(n-1)*(diff(y(t), t))

eq3 := diff(z(t), t, t) = -g-k*sqrt((diff(x(t), t))^2+(diff(y(t), t...

Been attempting this question for some time now and can't seem to get it right. 

Each time coming up with a different error.

It's part of our weekly homework, an extention question.

Write a procedure, marks, to take a student’s mark and output the appropriate grade, 

based on the following table:

mark       0-39.99          40-49.99           50-59.99          60-69.99            70+

For a math class, we have to create a roller coaster. Part of the coaster consists of two banked curves. I've tried looking it up but Maple isn't very clear on how to create the. So, how do you create banked curves in Maple?

I'm having trouble with the function G:=(n)-> 3 +2n-sum(sum(f(h), a=1..floor(m/2)), m=1..n) with base case G(0):=3, where h:=2a and f(h):=sum('f(2m)*3m, m=1..(h/2 -1).

For G(1), G(2) etc I get "Error, (in type/satisfies) too many levels of recursion" , note f(h) works properly. So I think the error is from the double summation. Any ideas what may be the problem?

Any help would be greatly appreciated.
