# Thread: [SOLVED] Intermediate Value Theorem

1. ## [SOLVED] Intermediate Value Theorem

Show that there is a root of the given equation in the specified interval.

cos x = x (0,1)

I'm getting f(1) < x < f(0). Is that right??

$f(x)=\cos x - x$ sub 0 and 1 in the function if one of the result is negative and the other is positive then there is a root in the interval (0,1)
