I am trying to express in case of 'variable two'

I tried to identify my answer wheter it is right by using excel.

But I don't know well. I think my answer is wrong.

Could you examine thath it is right?

I attached my files.

Thank you for reading my question

We cannot tell if you are doing something right if you don't tell us what you want to achieve!

You will have to explain what intend to do with your function xe(j). It seems that y2() is never user (ands its the same as x2() anyway and x and y will always be of same value. So it doesn't seem to make much sense to use y anyway.

Why don't you use Google translate to help you to more clearly state what you want?

In the meantime I had consulted my crystal ball to find out what may be after and I hope the attachment is of help.

Wow, maybe we need to collaborate our crystal balls

I was about to attempt this, but your attempt is nothing like I had in mind. A better explanation is required or at least the results he is expecting.

What jinsuk Lee is showing, sure is just a work in progress. He has asked similar questions before and I already pointed him to root and also to the solve block. But maybe because of a combination of lack of basic Mathcad knowledge and great difficulties to understand (my) English he(?) still sticks to his method of incrementing his variable by 0.1 until it exceeds a certain function value. Maybe he is doing this because it was the only way he found out doing it in Excel as his attached spreadsheet suggests.

As he is introducing two functions x2 and y2 now and obviously is solving for both variables x and y, I deduced (in fact my crystal ball did) he intends to change y2 to be different from x2 later and will then be searching for the values of x and y with x2()=x and y(2)=y which will give him some sort of threshold.

It sure would help if he could explain better what he is trying to achieve and what his goal is at the end, rather than posting an attempt and asking if its correct.

Are you trying to highlight the values of x2 which are less than the corresponding x value?

this file is my work.

I have experience difficult.

I mistake.

mu is 2/29, 3.5/29 ... 27.5/29, 29/29

You're trying to crate a vector of mu using i as an index. Your second mu in the list above is 3.5/29. so you asked i to be 1, 2.5 and so on. But 2.5 can't be a vector index, the index has to be integers.

But you have other problems: need to define phi, and a few other bits.

I've changed 1 thru 4 so they'll work, but Whether thet're correct . . . ?
