Derivatives are very useful. **Because they represent slope, they can be used to find maxima and minima of functions** (i.e. when the derivative, or slope, is zero). This is useful in optimization. Derivatives can be used to estimate functions, to create infinite series.

**Constant Rule and Power Rule**

- If f(x) = c, then f '(x) = 0.
- If f(x) = x, then f '(x) = 1.
- If f(x) = x
^{2}, then f '(x) = 2x. - If f(x) = x
^{3}, then f '(x) = 3x. - If f(x) = x
^{4}, then f '(x) = 4x.

Futures are **derivative financial contracts obligating the buyer to purchase an asset or the seller to sell an asset at a predetermined future date and set price**. A futures contract allows an investor to speculate on the price of a financial instrument or commodity.

**No.** **Derivatives are straight forward**. It's a misconception that it's hard or difficult.

**Application of Derivatives in Real Life**

- To calculate the profit and loss in business using graphs.
- To check the temperature variation.
- To determine the speed or distance covered such as miles per hour, kilometre per hour etc.
- Derivatives are used to derive many equations in Physics.

While **a chess puzzle is any puzzle involving aspects of chess**, a chess problem is an arranged position with a specific task to be fulfilled, such as White mates in n moves. Chess problems are also known as chess compositions because the positions are specially devised, rather than arising from actual games.

RBI pension will not be revised like Central pension; **an RBI Officer gets the same pension as on date of retirement till the end of life, DA (Dearness Allowance) increases**. After your retirement you will be allowed to withdraw part of the fund.

The induction motor slip is usually expressed as a percentage of synchronous speed (NS) and is represented by symbol s. Explanation: When the induction motor is stopped, the speed is zero. At **zero speed**, the slip is one.

Basic Trigonometric Formulas for Class 11**sin(π-A) = sin A**. cos(π-A) = -cos A. sin(π+A)=-sin A. cos(π+A)=-cos A.

**The different types of movement that are permitted at each joint are described below.**

- Flexion – bending a joint.
- Extension – straightening a joint.
- Abduction – movement away from the midline of the body.
- Adduction – movement towards the midline of the body.
- Circumduction – this is where the limb moves in a circle.

Most unicellular organisms, and a few multicellular organisms, **use cell division** to reproduce, in a process called asexual reproduction. In one organism produces one or more new organisms that are identical to itself and that live independently of it.

The main purpose of laboratory work in science education is **to provide students with conceptual and theoretical knowledge to help them learn scientific concepts, and through scientific methods, to understand the nature of science**.

For example, a 100 watt light bulb operating on 120 volts AC will have **144 ohms** of resistance and will draw 0.833 Amps.

According to Keynes' own theory of income and employment: "**In the short period, level of national income and so of employment is determined by aggregate demand and aggregate supply in the country**. The equilibrium of national income occurs where aggregate demand is equal to aggregate supply.

**The decimal numbers having infinite numbers of digits after the decimal point, and the digits are repeated at equal intervals after the decimal point** are known as the recurring decimal numbers. For example, \(0.111…, 4.444444…, 5.232323…, 21.123123… \) etc., are the recurring decimals.

Star topology is **a network topology in which each network component is physically connected to a central node such as a router, hub or switch**. In a star topology, the central hub acts like a server and the connecting nodes act like clients.

Third normal form (3NF)

Newton's I law of motion: **An object remains in a state of rest or of uniform motion in a straight line unless acted upon by an external unbalanced force**. Newton's II law of motion: The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the-force.
