![A graphing calculator is recommended.
Consider the following.
cos(x) = x3
(a) Prove that the equation has at least one real solution.
The equation cos(x) = x° is equivalent to the equation f(x) = cos(x) – x = 0. f(x) is continuous on the interval [0, 1], f(0) = 1
and f(1) = -0.4596976941
Since f(1)
<0< f(0)
V , there is a number c in
(0, 1) such that f(c) = 0 by the Intermediate Value Theorem. Thus, there is a root of the equation cos(x) = x, in the interval (0, 1).
