For example, to calculate online the derivative of the polynomial following `x^3+3x+1`, just enter derivative_calculator(`x^3+3x+1`), after calculating result `3*x^2+3` is returned. 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. The second derivative for arctan is \\frac{-2x}{(1+x^2)^2} No problem. Im trying to find the derivative of $\arctan(x-\sqrt{x^2+1})$ here are my steps if someone could point out where I went wrong. Then it must be the case that $$\tan \theta = x$$ What is Derivatives? $1 per month helps!! I don't want not only look in my Bronstein for the derivative, I want to calculate it on my own by using the theorem of the inverse function. If you have a function f(x), there are several ways to mark the derivative of f when it comes to x.The common way that this is done is by df / dx and f'(x).If a derivative is taken n times, then the notation d n f / d x n or f n (x) is used. The function is sometimes denoted arctanhz (Jeffrey 2000, p. 124) or Arthz (Gradshteyn and Ryzhik 2000, p. xxx). Tap for more steps... To apply the Chain Rule, set as . Let y = arctan(y) Then x = tan(y) Using implicit differentiation: 1 = dy/dx * (sec^2(x)) Since sec^2(z) = 1 + tan^2(z).....(see below end of proof) Several notations for the inverse trigonometric functions exist.
