how do i graph this sumation using wolfram alpha, i only know how to use desmos sorta.

should look like this sorta:

n=1n=22a2sin2(anx)=n(x)2=Ptot a=.29nm or .29109m tive and not sublimate it? P16.3 For the network of carotene modeled using the particle in the box, the position-dependent probability density of finding 1 of the 22 electrons is given by Pn(x)=n(x)2=a2sin2(anx) The quantum number n in this equation is determined by the energy level of the electron under consideration. As we saw in Chapter 15 , this function is strongly position dependent. The question addressed in this problem is as follows: Would you also expect the total probability density defined by Ptotal(x)=nn(x)2 to be strongly position dependent? The sum is over all the electrons in the -nework. a. Calculate the total probability density Ptotal(x)= nn(x)2 using the box length a=0.29nm, and plot your results as a function of x. Does Ptotal(x) have the same value near the ends and at the middle of the molecule
