i'm using "@" for "theta"Given that × = tan(@), find arcot(x) in terms of @

do the regular placeholder triangle:

Code: Select all

```
triangle:
.
, '|
, ' |
, ' | x
, '@ |
*----------------*
1
```

every triangle has 180* angle sum & this is a right triangle

get an expression in "@" for the third angle (at the top right)

then do the arccot(x)

(or use one of the idents here: http://brownmath.com/twt/inverse.htm )

(in the box just above "Functions of Arcfunctions")
