Complete Function Analysis - Algebra

Created by Adriweb

This is a world first! The program gives you all you need to know about a function ! In order to analyze a function, you have to enter its variable and its domain. For example, we'll take ln(x), defined on 0;+infinite. You will just have to enter : analyze(ln(x),x,{0,+oo}). (oo bzing the symbole of infinite, obtained by pressing Ctrl-i , complex i). Same for the funciton f(x)=x^2 on the specific domain [0,100], just type: analyze(x^2,x,{0,100}). The final given result is actually a matrix, due to a lack of programming capability on the NSpire. The matrix gives you the summary of what you need to know about the function. Zeros, Derivative, Limits, Variations... Note : The program should work with most common functions. If you notice any weird issue, please fell free to contact me and report the issue :)
