## How many solutions has "solve" found?...

Maple

I have 6 equations, eq1,...,eq6, with 6 unknowns a,b,c,d,f,g. I can find all the solutions with "solve".
If "solve" has found only one solution, then the ith solution number is given by sol[i]. For example,
c:=sol[3]. This comes from

sol:=solve({eq1,eq2,eq3,eq4,eq5,eq6},{a,b,c,d,f,g});

However, if solve has found more than one solution,
then the jth element of the ith solution is sol[i][j]. It is thus imperative to know how many solutions
the command "solve" has found. Also, how do we restrict "solve" to look only for real soultions?
Thank you very much!

## How do we check whether op(n,g) exists?...

Maple 13

I would like to check if op(n,g) exists for a given function g and a positive integer n.
How do I do it?
Naturally, I don't have the function g. It is theoretically created.
Thank you!

## Parentheses around y'(t) in Maple?...

Maple 13

Is there a way to remove the parentheses around y'(t)?

Thank you!

## How do we reverse the order of these two...

Maple 13

Assume that f:=(s+2)^2*(s-3). How do we get the order of the two factors reversed?
In other words, how do we get g:=(s-3)*(s+2)^2 by manipulating f? As usually,
I don't have f fixed. It is a product of two algebraic factors generated within the Maple program.
Thank you!

## Is there a command that will place singl...

Maple 13

I occasionally need single left quotes placed around the value of number.
Let's say x=3. Is there a command on x that will make x=`3`?
Thank you!
