We will find the … WebThis proves that differentiability implies continuity when we look at the equation Sal arrives to at. 8:11. . If the derivative does not exist, then you end up multiplying 0 by some undefined, which is nonsensical. If the derivative does exist though, we end up multiplying a 0 by f' (c), which allows us to carry on with the proof.
