Check out my post in Euler Avenue "Pi Day Challenge And Happy Pi Day"

#34 Re: Coder's Corner » Excel Calculators » 2013-03-17 01:03:05

I'm making one right now... when it's finished I'll tell you all the code.

#38 Re: Exercises » Pi Day Challenge And Happy Pi Day » 2013-03-16 22:45:51

It's all they tell me. There's another incomplete question. You have to find the area of the blue shaded area of a triangle with 10 equally tangent circles inside, but you can see the side or the radius.

There is an awesome challenge online. Since yesterday was pi day (March 14) they have something really cool.
www.pidaychallenge.com
3.14159265358979... Ok.
It's a series of levels where you have to answer lots of math questions.
Here are some of the questions below:
1. Name the first 5 decimal digits of pi.


3. (This is a trick question) What does the license plate say?

6A. The ___________ Theorem states that for any right triangle, the sum of the lengths equals the square of the length of the hypotenuse.

6B.
What is x?

9. What are the roots of the function

11. What is Archimedes' ratio approximation of pi?

I'm completely stuck on #23:
You run downwards at a speed of 3 steps per second.
It takes you 180 steps to get to the bottom.
You walk upwards at a speed of 1 step per second.
It takes you 20 steps to get to the top.
How many steps do you need if the escalator stands still?

#40 Re: Euler Avenue » Was mathematics invented or discovered? » 2013-03-16 10:44:38

I think it was invented, because numbers don't exist. They are a placeholder we use for a certain amount. They're not exactly one thing, if they were, shape-shifting could exist, because numbers would be everywhere. They're sort of a principle.

#43 Re: Coder's Corner » Set-Executionpolicy » 2013-03-02 00:37:31

Okay, so I tried

Get-Help Set-Executionpolicy

and it returned the following information:

NAME
    Set-ExecutionPolicy

SYNOPSIS
    Changes the user preference for the Windows PowerShell execution policy.


SYNTAX
    Set-ExecutionPolicy [-ExecutionPolicy] {Unrestricted | RemoteSigned | AllSigned | Restricted | Default | Bypass | Undefined} [[-Scope] {Process | CurrentUs
    er | LocalMachine | UserPolicy | MachinePolicy}] [-Force] [-Confirm] [-WhatIf] [<CommonParameters>]


DESCRIPTION
    The Set-ExecutionPolicy changes the user preference for the Windows PowerShell execution policy.

    To run this command on Windows Vista, Windows Server 2008, and later versions of Windows, you must start Windows PowerShell with the "Run as administrator"
     option, even if you are a member of the Administrators group on the computer.

    The execution policy is part of the security strategy of Windows PowerShell. It determines whether you can load configuration files (including your Windows
     PowerShell profile) and run scripts, and it determines which scripts, if any, must be digitally signed before they will run.

    For more information, see about_Execution_Policies.

    For more information, type: "get-help Set-ExecutionPolicy -detailed".
    For technical information, type: "get-help Set-ExecutionPolicy -full".

So I knew for sure you had to set yourself as administrator, but of course

And I can't get into setting myself as the administrator. Help!

So I tried the following code,

Get-Help Get-Executionpolicy

and it returned:

NAME
    Get-ExecutionPolicy

SYNOPSIS
    Gets the execution policies for the current session.


SYNTAX
    Get-ExecutionPolicy [[-Scope] {Process | CurrentUser | LocalMachine | UserPolicy | MachinePolicy}] [-List] [<CommonParameters>]


DESCRIPTION
    The Get-ExecutionPolicy cmdlet gets the execution policies for the current session.

    The execution policy is determined by execution policies that you set by using Set-ExecutionPolicy and the Group Policy settings for the Windows PowerShell
     execution policy. The default value is "Restricted."

    Without parameters, Get-ExecutionPolicy gets the execution policy that is effective in the session. You can use the List parameter to get all execution pol
    icies that affect the session or the Scope parameter to get the execution policy for a particular scope.

    For more information, see about_Execution_Policies.


RELATED LINKS
    Online version: http://go.microsoft.com/fwlink/?LinkID=113315

And that didn't contain any useful information.

I've just started PowerShell.
I've been testing out all my programs, but they didn't work.
We knew it must be the function

Set-Executionpolicy

so before we pasted one of my scripts from ISE,
we put

Set-Executionpolicy Unrestricted
Get-Executionpolicy

and it returned

Restricted

And I can't get into setting myself as the administrator.
Help!

Can someone help me with this pattern; I want it to be a fractal.
Start with the word "Wong".
Add "ong" after each consonant. "Wongononggong"
Do the same. "Wongononggongonongononggonggongononggong"

#47 Re: Coder's Corner » Coding » 2013-02-23 07:29:56

Microsoft Small Basic.
Now I'm starting
Windows PowerShell.
