Homework Statement A = {0, 1, 2, 3, 4 ,5} Let R be a binary relation on set A such that: R = {(0,1), (1,0), (1,3), (2,2), 2,1), 2,5), (4,4)} a. Make a Directed Graph for the relation R on A b. What must be added to R to make it reflexive/symmetric?

1. Find the normalization constant for the radial wave function for Hydrogen. I'm told that C = 1/(24a^5)^1/2 But how do I get that? 2. n=2, l=1 R(2)(1)=Cr^(-r/2a。) the integral from 0 to infinity of (x^4 * e^-"alpha"x) = 24 / alpha^5 3. I honestly don't know where to start
