Axis properties and line width reverts to some set of defaults each time my work recalculates the plot. Is there a way I can keep the axis properties and line width from changing each time recalculation occurs?

I've used LinearSolve(A,b) to find three unknowns. How do I assign these values to three named variables?

I assigned the resulting vector to a new one

V:=LinearSolve(A,b)

and then, one by one, assigned the elements to variables

C1:= V[1}

C2:= V[2]

C3:= V[3]

But there perhaps is a more elegant way to do this?

I've tried some simple uses of solve in MapleFlow without success. For example

solve(f=ma,a)

does not return

f/m

Does solve work in MapleFlow? Is there a problem with this Maple syntax in MapleFlow?

If I select Insert | Header Footer ... and choose the Custom Header tab, I don't see a way to create a multi-line header. How do I create a custom multi-line header?

How do I combine a number of functions into a composite one?

For example

Combined into a final composite function
such that the function R evaluates x and y as functions themselves.

Many times this sort of function definition makes it easier for the human.
