Quantum mechanics: how to sketch the wave function?

[Fatimah od]

huh ,, I confused !
would you like to draw an example ,, please !

 

[voko]

What is the value when x = 0? When x = a? When x = b?

 

[Fatimah od]

i think it's correct now ,,

No, that's not correct. You have one function, not two.

You have INTEGRATED the function over [0, b]. But you are unable to compute values of the same function in three points in the same interval. How is this possible?

 

[Fatimah od]

but the function is divided in the two interval , so how can I compute one function
I'm forced to express the function as two parts, I thought !!

 

[voko]

Your function has ONE value at any ONE point x. Not two, not three, not any other number.

 

[Fatimah od]

you mean A=√3/b ?

 

[voko]

At what point is that the value of the function?

 

[Fatimah od]

at "A" from the integrated

 

[Fatimah od]

all what I need to draw is the values which are on the y-axis
and that is to describe the wave function ψ

the problem now is " what is the function on (0,b)"?

I'm not sure if I can summate the two parts from (0,a) to (a,b) without any other operator such as "integral" ?

actually I think it's not correct two ,, it leads to a complicated formulas !
but that's what I could think about to get one function as what you said ,,, !!!

please ,
I need to more help ()
