# calc - visualise formula

Let's say I have two alternatives in columns `C,D`

like so:

```
row 6: sample size
row 7: sample mean
row 8: sample standard deviation
```

and then want to do a t-Test, which requires (amongst other things) calculating the degrees of freedom

```
C13 =( POWER( POWER(C8,2)/C6 + POWER(D8,2)/D6 ,2) ) / ( POWER( POWER(C8,2)/C6 ,2)/(C6+1) + POWER( POWER(D8,2)/D6 ,2)/(D6+1) ) - 2
(degrees of freedom)
```

where I have copied this obnoxious formula out of a book which provides them in nice, human-readable format, of course.

Let me put it like this: it looks correct when I stare at it for long enough, but no amount of staring will convince me that I haven't missed a mistake.

Is there a way to print this (libre office) formula in a more readable way for verification?
