Comma shift inverted

The only fix for this is a new keyboard.

You will need to set the correct keyboard on the PC. Alternativly try shift and the number 2 (on the top row of keys NOT the number pad)

use the email address without the " at the beginning and end... I suspect in your contact list it shows this email address WITH THE ".

Go into your contact list (address book), find this person's email address listing, and edit it to remove the "

Be sure that your keyboard is configured properly. You should be able to check under the "Region and Language" area of control panel if you are in windows and select "Keyboards and Languages." Check that it is set as a US keyboard or that it's set to which keyboard type you are using.

It sounds like num lock is turned on. On your keyboard hold the FN key and then press the symbol for num lock. This should clear the issue up.

The syntax of the command is

where function is the expression you are differentiating
x is the value of variable x at which you are evaluating the derivative, and tol is the tolerance (the error) you are willing to tolerate in the result.

If you do not want to specify a tolerance just omit the last comma and tol.

To enter the command d/dx you use key sequence [SHIFT][Integral]
To enter the symbol x in the expression you press [ALPHA][ ) ]
To enter a comma you use [SHIFT] [ ) ]
To enter a power of 10 in the tolerance use [x10^X] key

Example : Calculate

The key sequence is as follows
[SHIFT] [Integral] 3 [ALPHA] [ ) ] [X^2] [-] 5 [ALPHA] [ ) ] +2 [SHIFT] [ ) ] 2 [SHIFT] [ ) ] 1 [x10^X] [(-)] 12 ) [=]

DO NOT confuse [SHIFT] [ ) ] which enters the comma and [ALPHA] [ ) ] which enters the variable X

you need to change the keyboard lay out install US if the machine is from US and UK if bought in the UK goto regional settings etc

Go to the control panel > regional and language settings and make sure all are set to both US-English.

Go to control panel and check the regional and language settings. make sure it all says English and/or United States, if you are in the states that is, otherwise the keyboard will be different.

Your keyboard is probably set to the wrong region.

Start, control panel,Regional and language options,languages,details.

select united kingdom keyboard and delete the usa one.

this is right for XP - If your using Vista it might be different.

Also I bet the @ key will give you a " sign so this could be a temporary fix
