- If the screen does not show a login window, then nudge the computer Mouse and you will see a login screen come on; if not, try another machine.
- Type your
**login name**.*(Many computer systems are case sensitive, so type the proper upper or lower case for each letter.)* - Press the
**Enter**key. - Type your
**Password**(paying close attention to upper and lower case as well as special characters). - Press the
**Enter**key again.

**Double Click**with the Mouse on the*Maple*icon on the Right Hand Side Dock (looks like a fall maple leaf with an integral sign and an x. You should get a Maple window.- On your first attempt there may be a Maple introduction in the window,
so you can read it,or else you can get started running by clicking the
**File**Menu option near the top of the Maple Window, selecting the**New**SubMenu to pop up a Maple Worksheet*{you can also get a new worksheet by clicking the first tiny icon just below the word "File"; or you can get an old worksheet by clicking the second tiny icon in the row, called the "ToolBar", representing an "Open" file; the third one is to "Save"; and the forth is to "Print"; all options are also on the "File" Menu too}*. **Click**on the*white area*next to**>**prompt to make it ready of input as indicated by the Cursor mark.

*{Remark: you use the "Point & Click" method for each new Maple input line, not counting continued lines; to quit any window on a MathLab computer, click on the square button on the upper left corner of the Maple window and select "Close" in the pop up menu; to quit any window in MSWindowsXX as in PCLabs, click on the boxed "X" in the upper right hand corner of the Maple Worksheet.}*- For
**Maple Help**, after the > prompt type:> ?

and you should get the beginning help window on your screen. - For a
**List of Maple functions**, first click anywhere on the Worksheet window (note when you got the general help window, it became the*Key*window as indicated by the dark top bar of the help window; the*Key*window is the one where all your typed input goes), then type> ?lib

Again, to quit "Click" on the upper left button in MathLab, but upper right "X" in PCLabs MSWindowsXX. To merely change windows, click on the word "Window" and select your choice at the bottom of the menu. - For a short
**Maple Introduction**, first click anywhere on the Worksheet window, then type> ?intro

Again, to quit "Click" on the upper left button in MathLab, but upper right "X" in PCLabs MSWindowsXX. To merely change windows,

- For a simple
**Maple Arithmetic Example**, first click anywhere on the Worksheet window, then type> 1 * 4 / 2 -3;

The symbol "*" means multiplication, while "/" means division.-1

*{Semi-Colon Alert: Every Maple command line needs to be ended by a semi-colon (;), else Maple assumes you have not finished the line, even if you have pressed Return giving a new-line, and is waiting for continued input.}* - For another
**Maple Arithmetic Example**, first click anywhere on the Worksheet window, then type> 1 + 2 / 3 + 4^5;

The symbol "^" means exponentiation or raise to a power in Maple.3077/3

- For the
**Maple Floating Point Representation**of the previous answer, type> evalf(%);

1025.666667

*{Remark: The Maple function `evalf' computes the rounded 10 digit decimal form of its argument expression, which here uses the short hand notation percent sign, "%", for the previous argument, saving retyping; type `?evalf' to get more help or find out how to specify the number of digits, e.g., "evalf(%,16);" for 16 floating point digits.}* **For integrating in Maple**, e.g, 4*x^3 with respect to x, try> int(4*x^3,x);

4 x

**For defining a variable for repeated usuage in Maple**, you must use the ":=" instead of the usual equals "=" which is used for other purposes, e.g, 4*x^3 with respect to x, try> y:=4*x^3;

3 y := 4 x

**For plotting in Maple**, e.g, y with respect to x, try> plot(y,x);

but the answer comes up in a separate MaplePlot window.**For floating point solving in Maple**, e.g, a polynomial with respect to x, try> fsolve(x^3+x^2-3*x-3=0,x);

Note, here the equal sign "=" since means just an equation, distinct from the Maple definition ":=". Output:-1.732050808, -1., 1.732050808

**For defining Maple functions**, Maple uses the "mapping" notation for "f(x)":> f:=x->x^3+x^2-3*x-3;

f:= x-> x^3 + x^2 - 3 x - 3

**For Maple differentiation of f(x) with respect to x**, use the form:> diff(f(x),x);

3 x^2 + 2 x - 3

**For Maple integration of f(x) with respect to x**, use the form:> int(12*f(x),x);

3 x^4 + 4 x^3 - 18 x^2 - 36 x

For instance, click on "__NUMERICAL CALCULATIONS__" option in the New User's Tour and execute the following worksheet by pressing "Enter" at each Maple command line, starting with the restart Maple command line.*{Note that it is a good idea to start all your Maple worksheets with the***restart**command, since this clears all of Maple's former memory including errors and allows you to start afresh; in fact, if you are having Maple troubles restarting is a good idea, since the source of the trouble may be Maple's long memory of things no longer on your current worksheet.} - Or Click on MSCS Maple Help Page
- Or Click on Maple Help Page by Topic (MCS471 and other courses)
- Or you can copy and paste Maple commands to your own work sheet, by
- marking the Maple command line holding down the left mouse key;
**copy**by pressing "**Ctrl**" and "**c**" keys simultaneously;- switch back to your own Maple Worksheet by selecting it in the Maple
"
**Window**" submenu; **point and click**on the line that you want to use the new command in;**paste**by pressing "**Ctrl**" and "**v**" keys simultaneously;**execute**the new Maple command by pressing "**Enter**";- you can also edit the command line to make your own customized command;
- some other convenient control ("Ctrl") shorthands are
