### A sample session

### Numerical calculation
105/25;
interface(screenwidth=60);
100!;
interface(screenwidth=79);

### Built-in constants and functions
sin(Pi/2);

### Numerical evaluation
evalf(Pi,25);


### Manipulate basic algebraic expressions
expand((1+x)^2);
factor(%);

### Graphs
plot(sin(x),x=-Pi..2*Pi);
### Graphs needing xmaple rather than just maple
plot3d(answer,x=-Pi..Pi,a=0..1);
with(plots):
animate(answer,x=-Pi..Pi,a=0..1);

### Solve equations
solve(x^2-x=1,x);

### Trigonometry
cos(0);
tan(Pi/2);
expand(sin(a+b));
simplify((1+sin(x)+cos(x))/(1+sin(x)-cos(x)));

### Limits
limit((x^2-4)/(x-2),x=2);
limit(tan(x),x=Pi/2);
limit(tan(x),x=Pi/2,`left`);

### Calculus
Diff(exp(-x^2),x);
value(%);
Int(x^2*sin(x),x);
value(%);
Int(x^2*sin(x),x=0..1);
value(%);
evalf(%%,10);
