Class 11 Maths Chapter 13 Limits and Derivatives in the CBSE Syllabus include the following:
This section introduces the branch of Mathematics called calculus, derivative, limits and algebra of limits. Derivatives of certain standard functions are also discussed.
- Calculus is used in electrical engineering to find the length of wire to be used between two stations which are miles apart.
- Calculus is used to find the velocity and trajectory of an object.
- Calculus is used in operations research to improve efficiency and productivity and earn profits.
13.2 Intuitive Idea of Derivatives
This section defines the derivative of a function by giving a real-life example of distance travelled at different intervals of time.
The derivative is the rate of change at which one quantity varies concerning another. If one runs a business (say selling candies), derivatives can help one decide what quantity one should sell. The data on the business performance over the past few months is to be taken, and the trend needs to be analysed by plotting a curve. Derivative defines the instantaneous slope (dy/dx) of this graph.
The slope gives an idea of the marginal cost (change in cost/change in unit produced) of producing every additional unit at that instant. If this cost is greater than 10 bucks, that is the selling price, then a loss is incurred at the point.
For better clarity, refer to the table given below.
For 0-300 units, if the cost > sales, then it’s a loss
For 400-600 units, if the sales > cost, then it’s a profit
This section explains limits with an interesting example, left-hand limit and right-hand limit with solved problems.
If an ice cube is dropped into a glass of warm water and the temperature is measured with time, it is an example of a limit as the time approaches infinity. The time measured here is the temperature slowly attaining the room temperature where the glass was stored.
