atanhintermediate// Inverse hyperbolic tangent (input in (-1, 1))
Math.atanh(0) // β 0
Math.atanh(0.5) // β 0.5493...Use Math.atanh() to compute the inverse hyperbolic tangent of a number strictly between -1 and 1.
Math.atanh(1) returns Infinity because the function diverges as x β 1.
Challenge: Verify that Math.atanh(1) returns Infinity.
