10.2.22 Transforming inverse trigonometric functions into logarithms
Just as the trigonometric functions can be written in terms of complex
exponentials, the inverse trigonometric functions can be written in
terms of complex logarithms.
The atrig2ln command does this rewriting.
-
atrig2ln takes one argument:
expr, an expression containing inverse trigonometric functions.
- atrig2ln(expr) returns
expr with any inverse trigonometric functions replaced by
the appropriate complex logarithms.
