Not to long ago i found a post showing that maple was able to show the steps behind math.

example:

twostep:=proc(expr::uneval)
   (convert(expr,name) =
    subsindets(expr,And(name,satisfies(t->type(eval(t),constant))),
               z->convert(eval(z),name)))
   = eval(expr):
end proc:

a:=1:
b:=3:
c:=5:

h:=twostep(a+b*c);

                     (a+b*c = 1 + 3*5) = 16

However if I assign a unit to any of these numbers (a,b or c), the twostep code won't work.

Is there any way that maple can show the steps, while having it both show and convert the units?

example:

a:=70V:

b:=40Ohm:   (I can't insert the Omega sign)

c:= twostep(a/b);

                (a/b=70V/40Ohm) = 1,75A

 

It is possible to display something like:

4 + 3 = x - 1

without Maple actually adding the 4 and 3 and putting that as a 7?

 

Same idea with sqrt. Is it possible to write sqrt(9) in a worksheet and actually seeing it as square root of 9 rather than a 3. Maple automatically simplifies everything so it's kinda hard to show a step by step process. Is there a way to solve this problem?

To be clear, I am talking about typing this into an active worsheet line. I know I can do a lot of this if I just do text becuase text lines obviously don't execute. They just display text. The reason I need to have this working is becuase sometimes I would have a command line where I want some of it to be excuted and some of it not so I can't just use text.

Thank you

 

Hi There,

Im currently on using a trial version of maple for engineering students. I am looking to see how you can view a step by step method of solving equations. I can't seem to find a way of doing so and I keep just getting the final answer. Can you assist?

 

Also I can't find the quadratic equation option.

 

thanks,

Hi,
In maple18 has:

with(Student[Basics][ExpandSteps])

but how to see step-by-step factor ??

(Sorry! I'm not very good at English.)

Thank you!

lets say I have the folowng

a:=1

b:=3

c:=5

is it posible to have it like this

h:=a+b*c=1+3*5=16

How do I create an exptression with absolutely no evaluation?

I would like my students to practice the order of operations, so I want to be able to display an expression without evaluation of any of the operations involved. Is this possible somehow?
