The inverse tangent integral typically refers to the integral defined by the function: \\\[ \\int \\frac\{1\}\{1+x^2\} \\, dx = \\tan^\{-1\}(x) + C \\\] where \\( \\tan^\{-1\}(x) \\), also known as the arctangent function, is the inverse of the tangent function. The integral evaluates to the arctangent of \\( x \\), plus a constant of integration \\( C \\).
