The Dottie number is defined as the unique fixed point of the function \\( f(x) = \\cos(x) \\). This means that when you compute \\( f(x) \\) and set it equal to \\( x \\) (i.e., \\( x = \\cos(x) \\)), the value of \\( x \\) that satisfies this equation is known as the Dottie number. The Dottie number is approximately equal to 0.7390851332151607.
