# Thread: Hello everybody. i need some help with a formlua.

1. ## Hello everybody. i need some help with a formlua.

I have to apply a formula to a series of numbers
i have to finde out the arcsin for the next numbers

1. 1,03
2. 1,19

i have a long series of numbers and those too are the only above 1 numbers.
For the other i have used the excel arcsin but it is not working for this too.

Hello,

this impossible:
The domain of the arcsin-function ist $D = [-1,1]$, that means the arcsin-function is not defined for your values.

Thank you. i hoped could be something alse , maybe some other formula.
What will you suggest me to do? should i eliminate those values or should i try something alse.
The thing is like this:

I have this 2 values - 1,05 and 1,41 and in order to normalised them i have to apply too them the arcsin square root formula.
so i have run in excel first the square root and then i should apply the arcsin.
Do you have other abordation?

I am not that good in math.

maybe if you could describe the entire problem you are working on we could better understand what you are trying to do.
