They are different for a reason. One is differentiated the other is not. One is the question and the other one is the answer.
Your answer is also not simplified. In the beginning of this you differentiated it okay but then could not simplify it.
I will tell you what I will do. I will leave your thread open and someone else will help you.
You see how unhelpful you are being?
You TOLD me to differentiate the thing I just posted, I did it, I cannot simplify it, that is the whole point of this entire thread. I cannot simplify things, instead of helping me, you just tell me things like 'one is differentiated the other is not'. Thanks for all your help...I used to think you were a really good teacher. Not all students are the same so you must adapt your methods. Best wishes then.

You should end up with this.
Hi;
Since we are differentiating with respect to Pi, everything else is a constant.
Can you differentiate what is boxed off with respect to Pi?
So these two things, are they not different? Which is correct? I showed what I got by differentiating the bottom and wrote it out, it does not equal the thing you posted
]]>I am not doing anything on purpose. For one thing I can not always understand your input. When you do not latex math it is difficult to read.
Different methods give answers that are in different forms. They are equivalent. I have checked all of yours for equivalency with mine.
]]>You are missing the point of the comment. That was an honest mistake by me. I make them too. You have to know when you are right. In mathematics we can prove things for ourselves.
I need someone to break it down for me and show that the answer I provided at the beginning is correct. If you cannot do that, please stop trying to make me 'see the light' as it were, with all due respect, because I am getting frustrated that we are not communicating well enough and all this is doing it leading to confusion.
I am frustrated too but seem to have that under control. This is about the third time I have done this particular part of the problem. There is no breaking it down. You have some constants and a single variable to differentiate. For that you use the power rule. I have showed you this several times.
The last time you told me to just give you the answer because you do not have time to learn this. I have done that too. Also earlier, and this is exasperating, you said you got it. I forgot about the whole thread. Then you came back and said you do not understand it, so I did it again.
I also remember telling you that coming in sporadically for 2 minutes is not enough for me to teach you how. I can show you but you need to be here to learn it.
Mathematics is a prime subject. It is number one in difficulty, you are treating it as a side course. It takes 100% of my effort everyday.
Tell me what you want and I will do it. I can not do anymore than that. I can show you but only you can learn it.
One more thing, if you can argue with me about that differentiation like that then you know how to do it and I have been successful in teaching you no matter how irritated it made you. So please bear with my methods, they work!
I have taught two people and both of them are now better than I am at math. I am teaching a third person...
Let's do the 4th and last part.

Bobby, with all due respect, you are making this very difficult for me.
My answer to this question, which I just posted, you said I was missing a minus sign...then you posted your most recent answer, which completely contradicts what I said (so I must be wrong on the previous differentiation).
I need someone to break it down for me and show that the answer I provided at the beginning is correct. If you cannot do that, please stop trying to make me 'see the light' as it were, with all due respect, because I am getting frustrated that we are not communicating well enough and all this is doing it leading to confusion. If you are choosing not to help me, please do not reply.
]]>Yes, I know but he has to know that too.
]]>It looks like that is what he/she got...
]]>You should end up with this.
]]>Is it:
(nWYPi^(-n-1))/PP^(-n) = (nWYPi^(-n-1))/P^(-n+1)??
