Learn how you can calculate derivative as a rate measure in this video. You will learn how to apply derivatives in real life situations. You will use geometry and derivatives to calculate how to find the rate of change in the derivative. Being a math educator for close to three decades, I have tried to simplify this for you in this video. This topic is slightly tricky as you need to understand the problem first. For more videos on derivative as a rate measure or tangent and normal problems, you can contact me. This is a useful video for maths students of class 12. I am also available for online classes.in case you need to get your doubts clarified.
