I am new to Mathematica with experience in MATLAB, and I am frustrated with the long-winded introductory material focusing on syntax and functions irrelevant to my task at hand; I am asking for your help because I have not been able to find the documentation answering these questions. Given equations 1-4, I am trying to verify equations 7-11, 13-15:
[Edit: Regarding equations 13-15, partial derivatives of D, these forums are apparently not compatible with Windows 10 Microsoft Edge and image URLs get deleted erroneously when I Publish edits to the post, and won't let me include more than three images.]
This should be easy to do -- simply define the functions and execute a differentiation command -- but I am struggling both to learn the syntax, GUI, and functions to use.
Here is the code I have written so far trying to verify equation 11:
In[63]:= du = (Sum[v*d^(1/w), i])^w
Out[63]= (d^(1/w) i v)^w
In[64]:= m = (du - T)/(s*T)
Out[64]= (-T + (d^(1/w) i v)^w)/(s T)
In[65]:= D[1/Sqrt[2*Pi]*Integrate[Exp[-x^2/2], {x, -Infinity, m}], w]
Out[65]= (E^(-((-T + (d^(1/w) i v)^w)^2/(
2 s^2 T^2))) (d^(1/w) i v)^w (-(Log[d]/w) +
Log[d^(1/w) i v]))/(Sqrt[2 \[Pi]] s T)
It appears the sum is incorrect: What is this factor of 'i'? I am wondering whether I must use the product of two matrices since the summation is a sum in the physics sense, using subscripts, not in the technical mathematical sense as I see in the Wolfram documentation (in which the summation variable is explicit as a base or exponent).
I intend to continue reading and searching the documentation to try to accomplish this task myself, but I hope you will answer sooner so that I can proceed with my research sooner. Thank you for your time.
