## @acer  In these equations,  ...

In these equations,

e^(-34.32*10^4/t) means exp(-34.32*10^4/t),

I have tried to change e^(-34.32*10^4/t) to exp(-34.32*10^4/t), but they have the same result. I believe they have the numerical solution.

Thank you!

## It works! Thank you!...

It is very kind of you to help me, and it really works. I think I am not flexible enough to use maple.

Thank you again to help me.

## What about the values are in different l...

But if the values are in different length, such as:

m:=table([1=[151，153，160]，2=[157，152，153，150]，3=[161，158，152，155，156]])

What should I do to export it to excel, the export  instruction must be array or matrix.

## data changed, error appear...

If I change to another data, why it doesn't work?

Error is:

`Error, (in axycurve) invalid input: CurveFitting:-ArrayInterpolation expects its 2nd argument, p2, to be of type Or(list, rtable, numeric), but received fsolve(axycurve-cxycurve, 12600 .. 19300) `

## If r is an array or matrix, How to init...

Thank you for your help, I have another question.

If I want r to be an array or matrix, How can I initialize r?

## What about value y of intersection?...

hank you very much for your help, and it really help me a lot.

I have read your program carefully, some of them are not totaly understand.

1．Such as "axycurve := x -> CurveFitting:-ArrayInterpolation(axy, x, method = spline, extrapolate) "

It means I can get the new x and y which were splined. But how can I view value of x, y?

2．> fsolve(axycurve-cxycurve,min(ax)..max(ax));

> fsolve(axycurve-cxycurve,min(cx)..max(cx)); # extrapolation

Why they have different value? They should have the same value no matter from min(ax)..max(ax) or min(cx)..max(cx)

3．I have another question, If I want to know the (x,y) of the intersection, in your help I have calculate the x value, how could I calculate y value?

Thank you!
