Kitonum's Answer shows exactly what he wrote to create the plot. The lines in boldface are the literal code.

The normal distribution's CDF is not an elementary function and is usually expressed in terms of erf. What representation were you hoping for? 

@ncncnc23

My advice was intended for when A was created via output= plot, as it was before. But you've changed that to output= sequence.

@ncncnc23 

It seems to me like that would be a rather crowded plot. But if that's what you want, simply do

plots:-display(A); 

Speaking of tag management, I think that users with global editing powers should be able to remove garbage (i.e., nonspecific) tags from the tag database. The one that irks me the most is "query," but there are numerous others. 

@ncncnc23

To see the 34th plot, for example, just enter 

A[34]; 

If you decide on some format that you would like to use to see all the plots at once (such as animation or a tableau), then we can work on that.

For Posts and Questions I see the number of votes and the star but not the thumbs up. For Answers I see none of the three. I am using Android 4.4.2 on a Samsung Galaxy 5s.This is manifest in both Chrome and the AT&T browser.

Also, the option to vote on posts, questions, and answers is missing. 

I believe that what you want is the exponential distribution. 

Are you looking for an exact representation or a floating-point approximation?

@taro No, applyrule is definitely not powsubs.

@stddwrc Perhaps you could give us the original statement of the problem? It still makes no sense to me for the integration variables to be q, w, and e.

Since q, w, and e are procedures, I don't understand what you mean by using them as the variables with respect to which the integrations are done.

Do you not understand the error message? The differential order is 6: 3 from the Eq3 and 2 for theta and 1 for f from the Eq4. You have seven conditions. Eliminate 1 of them.

It's not big, but it is superlinear. But I'm not saying that it is a bad thing to do! I'm just saying that one has to watch out for seemingly trivial things which, if done in an inner loop, can add up. Note that converting a set to a list is relatively fast (but I can't figure out why it is not O(1).)
