## Test if question...

Maple 2022

I have a whole lot of conditions to test on the signum of answers. This gets difficult to read so I am wondering could something like the following be done?

```a, b, c, d := 1, -1, 1, -1;
if a, b, c, d = 1, 0, -1, -1 then
print("foo");
end if;
```

The above obviously doesn't work. The reason I would like to do this is it would be simple to read the patterns of 1's and 0's.

Any ideas?

## Select powers and coeffs on a general ty...

Maple

I was experimenting on and found coeff and degrees  do not work with algebraic type powers. So I set aboud dismanteling  a example polynomial. I certainly went around the houses doing this. I wanted to put the powers and coefficinets of x in an array.

I sure there must be a simpler way.

How should I handle the limit in the integration answe?. I don't see why it is necessary.

I would like to insert a hyperling to a geogebra document but the hyperlink box deosn't appear to allow general files. Can this be done?

## Problem with long description in a proce...

Maple 2022

I have a long description that contains some Maple commands.
I dont want to use # as the lines dont show up when i use

```Isee:=proc(a)
interface(verboseproc = 3);
printf("%P", eval(a));
end proc
```

The long description is. Any way around the problem?

```Test:=proc(A,B,C)  description  "Computes projective line through 2 projective points or intersert of 2 projective lines as a projective point or coincidence of piont  line
Does some checking on validity of inputs.
Mobposn:- Global Variable, must = 1 or 3.
Points are returned as <1,x,y> or <x,y,1>
Lines are returned as <z,x,y> or <x,y,z>,
normalgpt :- Global Variable must be 0 or 1.
Points with algecraic elements are not reduced to <1,x,y> or <x,y,1> if 0

print(A,B,A-C);

end proc;```
