Hi Loringh,
see, high exponents are +ve powers, while low exponents are -ve powers.
e.g. for 1200000=1.2X10^6=1.2E+6 (high exponents)
for 0.0000000012=1.2X10^-9=1.2E-9 (low exponents)
I think so easy ?

Thanks

How to do power exponent


You may have a caret ^, or X^y or Y^x. Enter the base, press the key then enter the exponent. If exponent is negative, precede it with the change sign key (-) or (+/-). To enter powers of 10 in scientific notation, use a key marked EE, or Exp, or x10^X

Cot(x) = -0.6


Let's start with a little background.

The cot(x) is also known as the cotangent(x) and it equals 1/tan(x) which equals cos(x)/sin(x). I'm showing these formulas because your calculator may not have a cot button but it will probably have buttons for tan, cos, and sin.

Your calculator may also have buttons for tan-1, cos-1 and sin-1. These are the inverse functions for tan, cos, and sin. If you enter a number and then push the tan-1 button, the result is the angle whose tangent is the entered number. For example, it you enter 1 and push the tan-1 button the answer will be 45 deg because tan (45 deg) = 1.

Now let's look at the problem, cot(x) = -0.6.
The first thing we need to know is do you want the answer in degrees or radians? Your calculator will have both modes. The default mode when you first turn it on is probably degrees. If this problem is in radians you will need to change the mode of your calculator over to radians before we start.

If cot(x) = -0.6, then tan(x) = 1/-0.6 from the formula I showed in the background section.

This means tan(x) = -1.6666666...

Now we just enter -1.66666667 and hit the tan-1 button to get the answer.

If we're operating in radians the answer is -1.0307 radians.
If we're operating in degrees the answer is -59.036 deg.

I hope this helps you out.

Assuming that the input numbers are given by the user:print "Menu"print "1. Addition"print "2. Subtraction"print "3. Multiplication"print "4. Division"print "0. Quit"
a = input("Please make a selection:")if a == 1: x = input("Please enter a number:") y = input("Please enter another number:") answer = x + yprint "%r plus %r = %r" % (x,y,answer)elif a == 2: x = input("Please enter a number:") y = input("Please enter another number:") answer = x - yprint "%r minus %r = %r" % (x,y,answer)
The same goes for everything else just with different signs. Don't forget that "*" is multiplication and "/" is division. Also, for 0. Just use:

I have installed win xp and when i m installing sound driver it tells that "no audio device found"


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}


Do the following steps to rectify this problem :
Step 1 .Reset the default BIOS settings:
You can try resetting the sound default in the BIOS. Here's how:
  1. Turn the PC on. When the Windows logo first appears, press the F1 key or Dell key repeatedly until you see the BIOS setup screen appear.
  2. Press the F5 key ( Setup defaults). In some other PCs depending on the manufacturer the BIOS at start-up will have one of the default options that have names such as - ‘Load Fail-Safe Defaults’ and ‘Load Optimised Defaults’.You will have to choose ‘Load Optimised Defaults’
  3. Select Yes or OK, then press the Enter key on your keyboard.
  4. Press the F10 key, then select Yes or OK to save the default settings. Press Enter.
  5. Exit the BIOS and restart your system checking for sound.
( For most PC's entering the BIOS will be the same but if it differs for your system, consult the operating manual for instructions on entering the BIOS.)

If this doesn’t work go to step 2

Step 2 . Configuring on-board sound in the BIOS:

Some computers come with sound on the motherboard (on-board), and some computers use a sound card. The on-board sound setting in the BIOS has to be set according to your particular sound configuration. Perform the following steps to correctly configure the sound in the BIOS:

Look at the back of your computer and use one of the following three items to determine the proper sound configuration and sound setting:
If the plugs for the speakers and microphones are located next to the parallel, serial, or USB ports, then the computer has on-board sound. The on-board sound setting in the BIOS should be Enabled. If the plugs for the speakers and microphone are located away from the other ports and sit in an area by themselves, the computer has a soundcard. The on-board sound setting (if there is one) in the BIOS should be Disabled. If the computer has sound plugs in both locations, a
soundcard has been added to the computer that already contains on-board sound. The on-board sound setting should be Disabled. To enter the BIOS, turn on the computer and when the first screen appears, press the F1 key /Dell key repeatedly until the BIOS Setup screen opens. Use the LEFT and RIGHT ARROW keys to select the Advanced tab. Press the DOWN ARROW key to select Onboard Audio Options and press ENTER. If Onboard Audio Options is not available, select I/O Device Configuration and press ENTER. If Audio Codec is listed, select it and press ENTER. Select either Enabled or Disabled depending on your configuration and press ENTER. Press the F10 key and then press ENTER to save and exit Start Windows and check for sound. If there is still no sound, continue to the next Step.

Step 3 . Reload the current sound driver

To do this, follow these steps
1.Click Start, type Device Manager in the Start Search box, and then press ENTER.
2.In the Device Manager dialog box, expand Sound, video, and game controllers.
3.Locate the audio device that was included with the computer.
4.Right-click the device, and then click Properties.
5.Click the Driver tab.
6.Click Uninstall.
7.Make sure that the Delete the Driver Software for this device check box is cleared, and then click OK.
8.In the Device Manager dialog box, click the Action menu, and then click Scan for hardware changes.
You should see a message that a hardware device is being installed. Additionally, the uninstalled audio device is now present in Device Manager.
9.Close the Device Manager dialog box, and then determine whether you can hear sound.

If your computer came with a motherboard CD, the audio drivers should be on the disk.

If you don’t have the CD go to your computer manufactures web page to search for updated sound driver software. Read the instructions on the download pages carefully
before installing.

If there are no updated sound drivers available, use Microsoft's Windows Update feature. Connect to the Internet and try the following items until Windows Update opens:

1.Click Start, and then click Windows Update (if it is listed).
2.Click Start, click Settings, and then click Windows Update (if it is listed).
3.Click Start, click All Programs, and then click Windows Update (if it is listed).
4.Go to Microsoft's Web site and click Windows Update from the Downloads menu.

Check if the sound works now….if it still doesn’t work then most likely the sound card might be faulty.

How to I use the exponential with I(t)=Ioe^-t/t


Actually, your function is not a function at all: it is a constant. In the denominator of the exponent, there should be another symbol, such as T but not t, because t/t is equal to 1. T is the period of the decay (half life.)

This being said, the exponential is represented by [e^x]. The syntax will depend on the calculator you have at your disposal.

To enter the exponential you need the change sign (negation) (-), and generally the whole exponent must be enclosed in parentheses

[e^x] [( ] ) (-) t [/] T [ ) ]
