## These groups are not symmetirc....

Use IsSymmetric(G)

Apply sort.

sort(lambda);

## Use Help...

Help -> Maple Help -> solve

or

?solve

## Use isolve...

Aplply isolve() to your inital equation.

This will give the variables a,m,n,x in terms of _Z1 and _Z2, both integers.

You can subst integer for say Z1 and then solve for Z2, etc .

## Use numeric option...

int(cos(3+sin(x)), x = 0 .. 5,numeric=true)

## Read Efficiency...

Look at help Statistics[Sample]

## This equation has no solution...

eq := -Pi/2 - arctan(25*x) - Pi = -(2*Pi)/3;

plot(lhs(eq)); ## shows the lhs is negative.

limit(lhs(eq), x = -infinity) ## shows the limit to be -Pi.

and -Pi < -2*Pi/3;

## In This example, just enter the expressi...

Maple2020

(a+b)(c+d+e)+(a+b)^3+(a+b+d)^2+c^2;
2+(1+d)^2+c^2

## Use explicit in solve...

eqs:=solve({fS,fV,fC,fR},{x1,x2,x3,x4},explicit); # No RootOfs

## Error in calculating known values...

The problem, as stated involved floating point values and associated errors.

In calculating the target position, an approximation was used.  The values obtained gave different slopes for the bearing lines.

Correcting the calculation of the slopes of the bearing line resulted in a better solution, to several decimal places.

Sorry for the noise.

## Help has an example...

help pdsolve[boundaryconditions] has an example that, on the surface, looks sililar.

## Try Help Set...

S := {W,X,Y};

S minus {X};
