Start Maple from Start Menu/Program Files/ or using the icon
in f:\math115. Note that the orange icon (classic worksheet)
is faster and has all of the features we need for this class.

Every Maple command must end with a semi-colon ";" for instance
>   2+1;
Every time I give you a command to use I will give the > symbol.
You are free to copy from this file and paste into maple, this
will ensure you don't make a mistake when typing it in.

Multiplication of numbers uses * and division uses /
Pick two integers and combine them using these two symbols.
Don't forget the semi colon! Notice that Maple does not use 
decimals by default, and neither will I, in class.

We can use ":=" to assign a value to a name, usually a letter
>   a := 7;
This is case sensitive, so we can set 
>   A := 4;
Set b to have a random value and determine the values of a+b, 3*a-b 
and 3*A-b. In the other labs I will use capital letters for matrices 
and lower case letters for numbers, but it isn't mandatory.

Use the function sqrt to determine the square roots of A and 3.
Notice that, similarly to fractions, square roots are left as is too.

We can use the command evalf to find the decimal value of a number.
If you want to know more about a Maple command, type
>    ?evalf
to exit from the help page, close the subwindow, or use the 
Window menu to move between them.

Use evalf to find the 25th decimal place in the square root 
of 3 and the 100th digit of Pi (note Pi, not PI or pi, both of which
are greek letters). 

Set lambda (a lower case greek letter) equal to Pi+Pi/2 and find 
sin(lambda) and the square root of the sine of lambda too.
I is a reserved letter in Maple, and so is D and some other ones.

Maple can also deal with polynomials:
>  p:=(2-x)*(x+5);

Use the commands expand(p), factor(p) and solve(p=0) to see the results.

Repeat with q when it is defined to be x^2-10

We can draw a graph of the functions
>   plot(q,x=-5..4);

Find how to draw both p and q on the same axes using help or guesswork

Use Maple to find for which values of x are p and q equal
