This helps to find the turning points of the graph so that we can find that at what point the graph reaches its highest or lowest point. To differentiate a function, we need to find its derivative function using the formula. Sync all your devices and never lose your place. Here x∈ (a, b) and f is differentiable on (a,b). If there is a very small change in one variable correspond to the other variable then we use the differentiation to find the approximate value. One of our academic counsellors will contact you within 1 working day. Calculus in Mechanical Engineering My name is "Jordan Louis If y' = f'(x) is in turn a differentiable function, then its derivative, df'(x)/dx, is called the second derivative of y with respect to x. Though the origins of integral calculus are generally regarded as going back no farther than to the time of the ancient Greeks, circa 200 B.C., there is some evidence that the ancient Egyptians may have had some hint of the idea at a much earlier date. FAQ's | In this chapter we will cover many of the major applications of derivatives. But it was not possible without the early developments of Isaac Barrow about the derivatives in 16th century. It is basically the rate of change at which one quantity changes with respect to another.
