AI Thread Summary
The discussion revolves around a request for assistance with MATLAB problems related to calculating the average linear density of a rod and finding Taylor polynomials for the function f(x) = tan(x). Participants emphasize the importance of showing prior attempts at solving the problems to receive help, as per the forum's homework guidelines. The moderators clarify that assistance is reserved for those who demonstrate effort in their inquiries, regardless of whether the problems are part of coursework or independent study. The conversation highlights the need for adherence to forum rules to foster understanding rather than simply providing answers. Overall, the focus is on encouraging educational engagement while maintaining the integrity of the forum.

MATLAB GEEKS (help!)

can someone solve this for me please?

The liner density in a rod 8m long is 12/sqrt(x+1) kg/m, where x is measured in meters from one end of the rod.

a) Find the average density of the rod.
b) Find c such that the function equals the average linear density of the rod and plot the function and the average density on the same plot.
c) Find the taylor polynomial for f(x)= tanx, at a= pi/4 for n=1, 3, 5 and in a new window graph the polynomials and the function on the same screen. Legend the graph.

Welcome to Physics Forums.

As per the homework guidelines, we can only help you if you provide a reasonable attempt at solving the problem yourself.

Show us what you have so far and we're more than happy to help you.
 


It's not a homework problem, my sister wants to solve all MATLAB probelms in her book and I'm tutoring her and can't help her solve this one.

Whilst I appreciate that may the case, it is irrelevant. I quote:
Physics Forums Guidelines said:
Homework Help:
On posting questions: Any and all high school and undergraduate homework assignments or textbook style exercises for which you are seeking assistance are to be posted in the appropriate forum in our Homework & Coursework Questions area--not in blogs, visitor messages, PMs, or the main technical forums. This should be done whether the problem is part of one's assigned coursework or just independent study. The reason for this is that the scientific and mathematical sections of Physics Forums are to be reserved for discussions and not academic assistance. Since graduate level assignments are meant to be more thought provoking (and hence more worthy of discussion), graduate level questions will be allowed in the relevant part of the main section of PF, provided that the graduate student attempts the problem and shows his work.

NOTE: You MUST show that you have attempted to answer your question in order to receive help. You MUST make use of the homework template, which automatically appears when a new topic is created in the homework help forums. Once your question or problem has been responded to, do not go back and delete (or edit) your original post.
The rules are in place to prevent cheating as well as to ensure that we simply do not dole out the solutions, but rather help students understand the topic itself.
