Q. When I try to download the .SIT file, it downloads as a .SAS file. How do I fix this?
A. This problem can be fixed by simply changing the extension back to .SIT once the program downloads.
Palm Program Registration:
Q. How do I access the registration screen in my new Palm software?
A. To access the registration screen, tap the menu bar at the top of any of the screens in your Palm software, select 'Options', and then select 'Register...'.
Q. How do I make the Palm software I just downloaded accept the registration code I received?
A. There are several things to remember when inputting your registration code:
- The code must be entered EXACTLY as it appears in the registration e-mail you received.
- The registration code is case sensitive. All letters, if applicable, in the code must be input in upper case.
- All of the "0" characters (if they show up in your registration code) are zeros, not the letter "O".
- Make absolutely sure that the "User" field on the Palm registration screen in TotalTrig/VectorCalc/Propagator is the name you provided as the Hotsync name when you bought the software. For example, if your Hotsync name ("User" name) is "John Doe" and there is one space between John and Doe on your Palm, and the name you registered the software with has two spaces, then the registration code will not work. Also, if your Hotsync name is "John Doe" and you registered the software with "john doe", the registration code you receive will not work.
- Make sure you do not put a user name in the "User" blank on the Palm registration screen. This name comes from when you first set up your Palm and is simply displayed here for your reference.
Q. What if I have not received my registration code and it has been more than two days since I registered the software?
A. Most of the time, when something like this happens, the email program you are using rejects mail because of a spam filter. Be sure and set your spam filter to accept email from where you ordered the software. Then email customer service from where you bought the software and have them resend your code.
Ordering Palm Software:
Q. How do I order from Multiology?
A. Simply click on any of the "Add to Cart" links on the Links, TotalTrig or VectorCalc pages. Transactions on this site are handled by PayPal and are completely secure, private and safe. If you've already added items, click the "View Cart" button to either view your cart or proceed to checkout. BE SURE and supply your Hotsync user ID from your Palm (see the FAQ for additional information) so a code may be generated for you. This can be added on the notes section of the PayPal screen. An unlock key will then be sent to you within two days.
Please note that clicking on any of these links will open another window, so be sure and temporarily disable your popup blocker if one is running.
Q. Can I order Palm software if I don't have a credit card or a Paypal account?
A. Yes, you can send a money order, check, or cashier's check to:
Multiology, LLC
121 Lou Ellen Lane
Harvest, AL 35749The money order or check should be made out to Multiology, LLC. Be sure to include an email address to which to send the registration code. If a money order or cashier's check is used, a registration code will be generated and sent no later than two days after receipt. If a personal check is used, the registration code will be sent once the check clears the bank.
Running Palm Software:
Q. What is MathLib and do I have to have it to run the software?
A. Multiology software requires that MathLib be installed, which is a free PalmOS shared library that provides a full set of IEEE-754 double-precision math library functions for Palm applications to use. If MathLib is not installed, an alert screen will appear, and the software will exit when the OK button is pressed. There is, however, a good chance that MathLib is already installed on your system and there is no need to install it again.
The MathLib.prc file is included in each distribution of software, so it may be installed as needed. It can be used with any OS 2.0+ Palm program and is distributed under the terms of the GNU Library General Public License. It is freely available with full source code and documentation at the MathLib Information (http://www.radiks.net/~rhuebner/mathlib.html) web page. It is not a part of the software program, and you are not paying anything for its use; a copy is simply included in the archive for your convenience.
Q. What is the small light purple rectangle in the lower right corner of the screen?A. This only shows up on some Palms and is the Graffiti Shift Indicator. It indicates in which input mode the Palm is -- upper/lower case, numeric/regular input.
TotalTrig Issues:
Q. The Arc-Length Solver screen is complaining that I am not entering correct values. Why?
A. Input values are constrained as follows, and an alert dialog will appear if any are violated.
- The angle (A) must be between 0 and 360 degrees.
- The arc length (s) must be less than 360 degrees times the radius (r).
Q. The Right-Triangle Solver screen is complaining that I am not entering correct values. Why?
A. Input values are constrained as follows, and an alert dialog will appear if any are violated.
- The hypotenuse (r) must be greater than the adjacent side (x) or the opposite side (y).
- The angle (A) must be less than 90 degrees.
- When the Area and hypotenuse (r) are input, there are situations where no solutions are found. For example, there is no valid solution when entering a "small" value of r and a "large" value of Area. If this happens, an alert dialog will appear.
- The Toggle button is used to toggle between the two triangle solutions possible when the Area and hypotenuse (r) are input.
Q. The Oblique-Triangle Solver screen is complaining that I am not entering correct values. Why?
A. Input values are constrained as follows, and an alert dialog will appear if any are violated.
- It is not allowed to enter the three angles only. There are an infinite number of solutions when only the three angles are input.
- If one or two angles are input, the sum of these angles must be less than 180 degrees.
- There are certain situations in which no solution is possible. For example, entering "small" numbers for sides a and b and a "large" number for Area will not yield a solution.
- If two sides and one of the angles opposite those two sides are input, there can be no solution, one solution, or two solutions. If there is no solution, an alert dialog will appear. If there are two solutions, then the toggle button will appear.
VectorCalc Issues:
Q. What does "[nan]" mean in the output field of VectorCalc?
A. "Nan" means "not a number". For example, if you only enter one vector (say A) you will get a [nan] in the Angle Betw. A & B field since there is no B vector.
Q. How do I enter a negative vector component or a negative exponent for a vector component?
A. To change the sign of a vector component, click the plus (or minus) sign between the colon and the vector component field. To change the sign of the exponent, click on the plus (or minus) sign between the "e" and the exponent field.
