# Quantum mechanics: how to sketch the wave function?

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

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

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?

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 !!

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

you mean A=√3/b ?

At what point is that the value of the function?

at "A" from the integrated

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 ,,, !!!
