I have defined my own function to implement inverse erf. I am trying to extend Maple so it recognizes basic identities. For example, I would like to Maple to simplify InverseErf(erf(x)) to x when x is real. I've used the following code in a module, but it doesn't seem to work (the evalf does work). Any suggestions?

ModuleLoad := proc()
global `evalf/InverseErf`;
global `erf/InverseErf`;
global `InverseErf/erf`;
`evalf/InverseErf` := proc(x)
local y,z;

I was trying to do some exercises on the Maplesoft site. (This site to be exact: http://www.maplesoft.com/applications/view.aspx?SID=1558&view=html ; 5.3.4. Example 4: Exercise 1:  Modify the above example so that it can be used to graph the sin

This is my question:

Given (1/6)*pi^2-(Sum(1/n^2, n = 1 .. N)) < 0.1e-2, how would would I find the smallest N such that the inequality holds?

I tried using solve command to no avail. Any suggestions?

Hi:

Say I have an expression like this:

a0:=I*(m*x+mp*x-omega[m]*t-omega[mp]*t);

I can factor out x,t and get an expected result:
collect(a0, [x,t]);

But how would I do it if I want to force Maple to act on the argument of exp?

a1:=exp(a0);

This doesn't work:
collect(a1, [x,t])

This will do what I want for this expression but maybe not in general:

I was doing some practice problems for Maple, when I encountered this problem:

My code is

w:=x+2+sin(x+2);

subs(x+2=u,w);

The output however did not change both `x+2`'s into `u`.

The output was: x+2+sin(u)

Any ideas as to why? Thanks in advance.

we were given three questions to do, i got the other two ones out grand but ive been trying to do this for hours and i still don't get it.   it is 

Write a function that produces the power set of a given nite set M, i.e. the set of all subsets.

Thusyour function has

Argument: a finite set M,

Returnvalue: the set of all subsets of M.

Examples: If PP is the procedure,PP({}) returns {{}},PP({a}) returns {{},{a}},PP({a,b}) returns {{},{a},{b},{a,b}},PP({a,b,c}) returns {{},{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c}},PP({a,b,c,d}) returns{{},{a},{b},{c},{d},{a,b},{a,c},{a,d},{b,c},{b,d},{c,d},{a,b,c},{a,b,d},{a,c,d},{b,c,d},{a,b,c,d}}.

you will be rewarded with a lifetime supply of grattitude if you can help me out! thanks.

Hi,

I need help for the following,

Solve the equation :x=(2012-x)^1/2(2013-x)^1/2+(2013-x)^1/2(2014-x)^1/2+(2012-x)^1/2(2014-x)^1/2

Solve Differential Equation: y''-3y'-4=e^xsin4x

has anyone successfully installed maple 17 on a machine running ubuntu 13.04? 

Wolfram Alpha has a normalcdf() function, which with parameters reads: normalcdf(x₁, x₂, µ, σ). How would I go about acheiving the same in Maple?

Hi,

Suppose i have 2 dimensional array of size (10,3), and what i need is to plot , first column with respect to second or third column. I dont know whehter it is possible or not. Please help me.

Thanx and regards

I tried to install Maple 17 on my MacBook Pro 13" early 2011 w. Mountain Lion 10.8.5.
It always freezes, I can't press anything but the button animation is slowly blinking.

I'm stuck on the "Installation Setup".

Can someone help me solving this?

Hi,

I am trying to solve equation in the form of

We are writing object oriented packages, so we have various objects containing static export'ed methods, as recommended in Maple OO docs.  But if foo is an object, exports(foo) only shows the non-static exports, which is not very useful.  How can a user discover the static exports that are available for an object?

Thanks,

Tracy.
