WebMar 24, 2024 · The inverse hyperbolic tangent is a multivalued function and hence requires a branch cut in the complex plane, which the Wolfram Language 's convention places at the line segments and . This follows from the definition of as (1) The inverse hyperbolic tangent is given in terms of the inverse tangent by (2) (Gradshteyn and Ryzhik 2000, p. xxx). WebWait! We need to offset each spike with a phase delay (the angle for a "1 second delay" depends on the frequency). Actual recipe for a frequency = a/4 (no offset) + b/4 (1 second offset) + c/4 (2 second offset) + d/4 (3 second offset). We can then loop through every frequency to get the full transform. today dr phil
