The inverse hyperbolic tangent tanh^(-1)z (Zwillinger 1995, p. 481; Beyer 1987, p. 181), sometimes called the area hyperbolic tangent (Harris and Stocker 1998, p. 267), is the multivalued function that is the inverse function of the hyperbolic tangent. `lim_(x->+oo)arctan(x)=-pi/2` The arctan function allows the calculation of the arctangent of a number. 3 * ln(2) * 8^x, comes from the fact that we must use the chain rule, and hence we take the derivative of what's inside (8^x). A reference triangle is constructed as shown, and this can be used to complete the expression of the derivative of arctan(x) in terms of x. Assuming we know the derivative of tan(x) is sec 2 (x): Let y = arctan(x) so that x = tan(y). Thus the gradient of atan2 is given by â (,) = (â +, +).

But don't forget to use the Chain Rule in your problem!! Find more Mathematics widgets in Wolfram|Alpha. Taking the derivative of the second expression implicitly gives: solving for the derivative gives: (1) This is correct but unsatisfying - we want the derivative in terms of x. The function is sometimes denoted arctanhz (Jeffrey 2000, p. 124) or Arthz (Gradshteyn and Ryzhik 2000, p. xxx). Tap for more steps... Rewrite as . (This convention is used throughout this article.)
