Q

The Squeeze Theorem

A

Don’t know the definition, but you’re supposed to find the range of the function (usually sin or cos, so between -1 and 1) so it is in the format -1

Rolle’s Theorem

A

If f(x) is continuous on [a,b], if f(x) is differentiable on (a,b), and if f(a)=f(b), then there exists a value c in (a,b) such that f’(c)=0.
