Derivatives have a wide range of applications in engineering, sciences, social sciences, economics and other applications. In this blog, we discuss Derivative as a Rate Measure. Visit Class 12 Differential Calculus, for more resources.
This topic is slightly application oriented, hence students tend to find it a little difficult. However, this post will cover all the topics and formulas that you would need to know along with problems.
dy/dx represents the Rate of change of your w.r.t x. If y increases, dy/dx is positive and if y decreases, dy/ dx is negative
Try this question!
A ladder 5 m long rests against a vertical wall. If the top of the ladder slides downward at the rate of 10 cm/sec. find the rate at which the angle between the floor and the ladder is decreasing when the lower end of the ladder is 2 m away from the wall.
How about this problem?
Find the coordinates of a point on the ellipse where the ordinate decreases at the same rate at which the abscissa increases.
