for the definition of the principal values of the inverse hyperbolic tangent and cotangent. In these formulas, the argument of the logarithm is real if and only if z is real. For artanh, this argument is in the real interval (−∞, 0] , if z belongs either to (−∞, −1] or to [1, ∞) .
For the above isosceles triangle with unit sides and angle , the area 1 / 2 × base × height is calculated in two orientations. When upright, the area is sin θ cos θ {\displaystyle \sin \theta \cos \theta } .

The purple curve and circle is the image of a small circle around the branch point z=0; the red curves are the images of a small circle around the point z=-1/e. The range of W 0 is inside the C-shaped black curve. The range of each of the other branches is a band between two black curves that represent points on the negative real axis (a black ...
