Thank you!!!
oh,it was a mechanical error) Thanks, but I need an interval or coordinates of rectangle, where these rectangles overlap. how to find it? ![out][1] [1]: /c/portal/getImageAttachment?filename=prog2.png&userId=237134
Hello! Help me please to draw a graph of the results of my procedure in 3D . The procedure displays a graph of the function Sin[x] and rectangles on it and Ln [y] and rectangles on it . I need to print a sum of procedsure's results of Sin[x] and...
Thanks! Exp works! but unfortunately, Log doesn't work, though I edited spxey = {0.75, 2.5, 4.25, 6}; and data = Table[{x, f[x]}, {x, 1, 6, 0.1}]; Can You help me?
Thank You!
I'm sorry for bothering..... It was the 1-st step of my algorithm. Tell me **please**, how on the 2-nd step of algorithm **to find intervals** roots **separately** **in** the 1-st found interval **{2.11731,3.3125}** **and in** the second...
**Many Thanks!**
There are no standard function, so I tried to do by this way: but then iterations are not printed on each step     HELP;(      [mcode]step[f_, iter_, {a_, b_}] :=       Module[{inter = Interval[{a, b}],x =(a+b)/2},        Print["Iteration ", iter,...
I have to write the Newton's method  in the point which is the mean of Interval. and in 'While' loop  it could be while the function(point)>eps.[mcode]point = Mean[inter]; step[f_,inter_] := Module[{p:=Mean@First@(List @@ inter)},...
