- Understanding the integral of 1 (1+x^2) • Physics Forums
The integral of 1 (1+x^2) is indeed arctan(x), and no substitution is necessary to find this antiderivative since the derivative of arctan(x) is 1 (1+x^2) Substituting x with tan(Θ) transforms the integrand but can complicate the process unnecessarily, as the antiderivative is already known Understanding the substitution method is valuable, but it is essential to recognize that the goal is

- How to derive the derivative formula of arctan x? - Physics Forums
To derive the derivative formula for arctan x, start by letting y = arctan x, which implies tan y = x Using implicit differentiation, the derivative dx dy is found to be sec² y Applying the Pythagorean identity sec² y = tan² y + 1 leads to the expression dx dy = x² + 1 By flipping the fraction to find dy dx and substituting tan y with x, the final result is confirmed as dy dx = 1 (1
