Question about Microsoft Windows Vista Ultimate Edition

Hello. I am taking online college classes and when using the lab program for algebra, the symbol for pi and the - symbol both show up as a box.

I have tried contacting tech support for the program, my college, and have tried installing Firefox browser to use. So far no-one can help.

Also, I use Windows Vista.

Please help, this is stopping me from completing some of my homework and tests, since I can't tell the difference between the two symbols.

I can be reached here or at whttail101@yahoo.com

Dean

Go to the character map and find the font which have both symbols, then use that font when taking online class

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

If you want to square an expression enclose it in parentheses and raise to the second power.

The calculator does not have a Computer Algebra System or CAS: It cannot handle non numerical quantities. Every letter symbol must have a value stored in it prior to being used. If no value is stored in a letter symbol, value 0 is assigned to it. Sorry.

As to calling Pi a variable, I would not got that far, even if the calculator would give me 2Pi.

TI calculators that have a CAS are the TI92 Plus, the Voyage 200 PLT, and the TI Nspire CAS, TI Nspire CX CAS.

The calculator has two Input/Output Modes: The MathIO and LineIO modes. Line IO is the old input mode where all symbols are written on a single line. MathIO permits fractions to show as they would in a textbook (a horizontal fraction bar and two squares, one on top and the other at the bottom. Pi can be used as Pi and irrational square roots are displayed with the root symbol. etc,,

If you are in MarhIO and you get a result with fractions, radicals, or pi. you can readily convert it to its decimal approximation by pressim the SD key. If you enter some expression with fractions and radicals and you do not want the result displayed with fractions or radicals you press SHIFT = instead of =,

Now if you do not care to have ANYTHING displayed as a fraction, radical or with PI, just set the IO mode to the old LineIO.

To effect that, press SHIFT MODE to enter the SETUP. Select 2:LineIO. From that moment on you will no longer see a fraction, nor a radical nor PI, e,

If you ever reset the calculator, the MathIO mode will be restored as default IO mode.

Use the fact that cos(pi/4)=sin(pi/4)= 1/square root(2). Trigonometric identity cos(a+b)=cos(a)cos(b)-sin(a)sin(b).

Hello,

Sorry to disappoint you but you cannot do it due to the fact that the representation of irrational (SQRT(2), ..) and transcendental (e, pi, etc.) numbers on a calculator or even a computer is approximative : a number like sqrt(2) has an infinite number of decimal digits while the number of internal digits a calculator uses to store results is limited (10, 12, 15 or even 24).

Once an irrational or a transcendental number has been**evaluated numerically** it generally ceases to be exact.

If you want to manipulate algebraic expressions, you need a calculator that has a CAS (computer algebra system) operating system and a**symbolic algebra **option.

Some exemples of calculators with a CAS are The TI nspire CAS, the HP 48 series, HP 49, HP 50, Casio ClassPad3xx, the TI 89titatium, the TI Voyager 200PLT, the TI 92 and Ti 92Plus. The ones with a fullblown keyboard might not be accepted on certain standardized test.

You may also try to get some emulators on the Internet for the HPs or the TI 8xx and play with them on the computer.

Hope that helps.

That will not help. They show up as a square when I type answers, and they show up as squares in the question that is generated by the lab.

Another bit of information I thought of, when I type passwords for yahoo, they show up as squares too, not as asterisks. They used to show up as asterisks, but one day they started showing up as squares, which I didn't think anything about it, I just thought it had to do with a vista patch. Some websites they show up as squares, and others show up as dots.

Anyone else have any help for this problem?
