Using the Calculator
Tap numbers and functions in Calculator just as you would with a standard calculator. 
When you tap the add, subtract, multiply, or divide button, a white ring appears 
around the button to let you know the operation to be carried out. Rotate iPhone to 
get an expanded scientific calculator.
Standard Memory Functions
• C:  Tap to clear the displayed number.
• MC:   Tap to clear the memory.
• M+:   Tap to add the displayed number to the number in memory. If no number is in 
memory, tap to store the displayed number in memory.
• M-:   Tap to subtract the displayed number from the number in memory.
• MR:   Tap to replace the displayed number with the number in memory. If the button 
has a white ring around it, there is a number stored in memory.

							Scientific Calculator Keys
Rotate iPhone to landscape orientation to display the scientific calculator.
2ndChanges the trigonometric buttons (sin, cos, tan, sinh, cosh, and tanh) to their inverse 
functions (sin-1, cos-1, tan-1, sinh-1, cosh-1, and tanh-1). It also changes ln to log2, and ex to 
2x. Tap 2nd again to return the buttons to their original functions.
( Opens a parenthetical expression. Expressions can be nested.
) Closes a parenthetical expression.
% Calculates percentages, adds markups, and subtracts discounts. To calculate a 
percentage, use it with the multiplication (x) key. For example, to calculate 8% of 500, 
enter 
500 x 8 % = 
which returns 40.
To add a markup or subtract a discount, use it with the plus (+) or minus (–) key.   
For example, to compute the total cost of a $500 item with an 8% sales tax, enter 
500 + 8 % = 
which returns 540.
1/x Returns the reciprocal of a value in decimal format.
x
2Squares a value.
x
3Cubes a value.
y
xTap between values to raise the first value to the power of the second value.   
For example, to compute 34, enter 
3 yx 4 = 
which returns 81.
x! Calculates the factorial of a value.
√ Calculates the square root of a value.
x√yUse between values to calculate the x root of y. For example to compute 4√81, enter 
81 x√y 4 = 
which returns 3.

Wi-Fi
Wi-Fi settings determine whether iPhone uses local Wi-Fi networks to connect to the 
Internet. If no Wi-Fi networks are available, or you’ve turned Wi-Fi off, then iPhone 
connects to the Internet via your cellular data network, when available. You can use 
Mail, Safari, YouTube, Stocks, Maps, Weather, the iTunes Store, and the App Store over a 
cellular data network connection.
Turn Wi-Fi on or off:   Choose Wi-Fi and turn Wi-Fi on or off.
Join a Wi-Fi network:   Choose Wi-Fi, wait a moment as iPhone detects networks in 
range, then select a network. If necessary, enter a password and tap Join. (Networks 
that require a password appear with a lock 
 icon.)
Once you’ve joined a Wi-Fi network manually, iPhone automatically joins it whenever 
the network is in range. If more than one previously used network is in range, iPhone 
joins the one last used.
13 9Chapter 19    Settings 
						

							When iPhone is joined to a Wi-Fi network, the Wi-Fi  icon in the status bar at the top 
of the screen shows signal strength. The more bars you see, the stronger the signal.
Set iPhone to ask if you want to join a new network:  Choose Wi-Fi and turn “Ask to 
Join Networks” on or off.
When you’re trying to access the Internet, by using Safari or Mail for example, and you 
aren’t in range of a Wi-Fi network you‘ve previously used, this option tells iPhone to 
look for another network. iPhone displays a list of all available Wi-Fi networks that you 
can choose from. (Networks that require a password appear with a lock 
 icon.) If “Ask 
to Join Networks” is turned off, you must manually join a network to connect to the 
Internet when a previously used network or a cellular data network isn’t available.
Forget a network, so iPhone doesn’t join it automatically:   Choose Wi-Fi and tap 
 next to a network you’ve joined before. Then tap “Forget this Network.”
Join a closed Wi-Fi network:  To join a Wi-Fi network that isn’t shown in the list of 
scanned networks, choose Wi-Fi > Other, then enter the network name. If the network 
requires a password, tap Security, tap the type of security the network uses, and enter 
the password.
You must already know the network name, password, and security type to connect to 
a closed network.
Some Wi-Fi networks may require you to enter or adjust additional settings, such as a 
client ID or static IP address. Ask the network administrator which settings to use.
Adjust settings to connect to a Wi-Fi network:   Choose Wi-Fi, then tap  next to a 
network.
VPN
This setting appears when you have VPN configured on iPhone, allowing you to turn 
VPN on or off. See “Network
” on page 143 .
Notifications
This setting appears when you’ve installed an application from the App Store that uses 
the Apple Push Notification service.
Push notifications are used by applications to alert you of new information, even when 
the application isn’t running. Notifications differ depending upon the application, but 
may include text or sound alerts, and a numbered badge on the application’s icon on 
the Home screen.
You can turn notifications off if you don’t want to be notified or want to conserve 
battery life.
Turn all notifications on or off:   Tap Notifications and turn notifications on or off.
