It used to be that questions/posts were put into a subfolder that users had to click into.  If we had a spam folder where initial posts of spam could be filtered off into that folder maybe it would be easier managed and the majority of users wouldn't have to bother even seeing the messages.

Re: delete as spam.  If someone accidentally or someone maliciously decided to spam delete the wrong user, say someone who has made substantial contribution to mapleprimes then all of his posts would get deleted (not good).  Alternatively if a normal user happen to post a user story which was classified as spam, it may get deleted along with the rest of his/her posts. 

I would suggest not linking any previous posts by the user so that they are not to be deleted in case of such errors.

@acer the server I am on has restricted javascript so I cannot run any apps in the browser on mobius or run the maplecloud.

All I need would be a viewer, just a pdf version of the worksheet.  I could provide the file to members here to do it but I don't want to have to do that all the time. 

@Leighmm No, I don't believe you can.  I've been pushing for this option for a few releases now.  There may be a workaround. 

@tomleslie it's easy to understand his confusion once it's all layed out, but was trying to not give him the direct answer right away. 

@ecterrab ah yes, thanks.

Using the answer you got

a := (-1/2+exp(2))*(x-2)-ln(2)+exp(2)

simplify(a)

evalf(%,3) # evaluate the last expression to 3 decimals

@al-faraj that is correct

the equation of the tangent line for f(x)=-ln(x)+exp(x) at x=2 is that.

y=6.89x-7.1

your commas instead of decimals were confusing.

@al-faraj Just simplify and you'll be fine.

@al-faraj what answer are you expecting?

Should we delete them or leave them for mapleprimes facilitators?

I've seen it happening a lot in the last few weeks.

I think mapleprimes needs to add captcha's when people create new accounts.  That might help

@Noor2015 You are seeing a summarized version of a matrix.

To view the matrix after execution you need to set interface(rtablesize=500) or some large number if you want.  

Or right click on the matrix summary and choose browse to view the values.

@Preben Alsholm yes thanks that is what I was looking for.  

I thought you were involved in the answer.  You were one of the users I searched the answers for but couldn't find it or I missed it.

Indeed if replies were shown I would have probably found it.  Users answers don't show replies nor is there a list containing replies.

@Carl Love if you do find it please post the link.  I think the original ops question was rather vague which is making it difficult to find.  I can't recall who was involved in the answer but it could help.  I'm pretty sure it was posted within this year (2015).  Key wording in the question would help me find it but I can't remember more than the animation and I don't think he used the word earthquake either.

There was an 2d animation of a house moving back and forth on ground that was also moving but slightly out of phase.  I looked in a few users answers but no luck yet.  anyone?
