We prove that f(x)=sqrt(x), the square root function, is continuous on its entire domain where it is real, from 0 to infinity including 0. We complete this proof using the epsilon delta definition of continuity of a function at a point. To do this, we simply take an epsilon greater than 0 and an arbitrary point c from our domain, then go ...

How can we find the area of the triangle with 3 given sides? In this geometry tutorial, we will see how to use Heron's formula to find the area of the triangle whose sides are 11, 13, and 20. Note that this is also a "Heronian triangle" because both its sides and area are positive whole numbers. We will also learn the proof of the formula ...

We go through a classic example of applying Rolle's theorem to demonstrate a cubic equation has only a single root. To do this we use the intermediate value theorem to establish the existence of a single root, then use Rolle's theorem and a proof by contradiction to establish there can be no other root. #calculus1 #apcalculus Join Wrath of Math ...
