Hello Mr Bill, Sorry again If I distrubed you ,but i really need your help in solving my Mathematica program , I wrote the explanation of my job in the PDF in details ,may that help you to understand what Iam looking for ,and thank you again of your help.
Mr Bill I tried to find the value of (w=T) which makes the determinte =0 when R=5,a=3.116.S=8.2 by using FindRoot and I got that w= 2548.33 but when I used this value I did not get zero for the determinte and that which made me puzzled and confused added to that the right value of w should be...
Compare between my handwriting & mathematica
Mr Bill ,thank you very much for helping me alot, I sent the new equations in my handwriting ,I hope it will better this time to compare with what I wrote in mathematica
Sorry Mr Bill ,but I think that you did not notice that in my hand writing I wrote that
m= (S+(h(w^0.5)+aR)(1-t) & K= a^2 w(1-t) so when you susitute them in the equations you will find that they are the same what I wrote in Mathematica
Hello,I need help in Mathematica,my problem is that I wrote the system of differential equations and I put a certain value of the variables and it is supposed that the value of the absolute of the determent would be zero but unfortunately I did not get zero , I got another answer
when I put...
problem in findroot
Hello Mr Bill,thank you again for your help ,my new code is the same like before but with the change of the differential systems but I faced a problem when I used Findroot function,my system works but when I add the FindRoot Function the program did not response,so I hope to...
Hello,I have a problem in writing my code in Mathematica, when I put values of R,T,S&a the system worked and gave me result but when I put the system in for loop , it gave me errors,I hope someone help me and thank you
Help me Mathematica
Hello Mr Bill ,thank very much for your help and I want to tell you that I found another way to find the minimum values but also I faced a problem in the range of FindRoot function ,I got the minimum values for Q= 0,10,20,30,40,50 but after 50 the program stops and gives me...
Mr Bill ,I want to ask you about the code you wrote to me in the last time,I tried to find the
minimum zeros for more than 30 but the code gives me that the bisection failed ,also at a=30 there is no minimum values because the the values are decreasing ,so we have to put in our mind that for...
Hello Mr Bill,thank you very much for spending your time in solving my problem ,I know this method you used is not the best one but at least it works.Now my quation is if I want to find the minimum for more than 30 what changes I will have to do ? just change the interval a<=100 instead of...
As you see the results when Q=0, a=3.7&w=93439, a=3.9&w=92933, a=4.1&w=93086 w decreases then it increases so the smallest value of w that makes Temp=0 is 92912 when z=3.95 and that what I want to get
Hello Mr Bill you did not understand me
I want to find the smallest value of w which makes Temp is zero for a certain value of z
When see the results of w it first it decreases then increases so for sure there is a minimum value of w that makes Temp=0and that what Iam looking for
Thank you
Hello,Mr Bill,thank you for simplified my code,now I have still something to accomplich which is using FindMinimum function,I do not Know how to use it to find the minimum value of w (the result of the FindRoot function)and the value of a.As before I gave an example:
we have
Q a...
Mr Bill thank you for your help and spending your time to solve my problem,but I really need somebody's help in the Mathematica espacially that it is the first time I use it and My Doctors at my university do not have a lot of experience using it. So I really need your help and do not take the...
