Web1 lug 2016 · An accurate approximation is fine, I would prefer up to 16-decimal accuracy if possible. $$ x \arctan (x) = 0.5 $$. Using Excel and some guessing I can see that the answer is approximately $0.765378926665789$, but I want to be able to calculate this quickly when changing the variable y.

The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45 ... teardrop kitchen
