Summary: Your TI-83 or TI-84 **can't differentiate in symbols, but it can find the derivative at any point by using a numerical process**.

Finding a second, third, fourth, or higher derivative is incredibly simple. **The second derivative of a function is just the derivative of its first derivative**. The third derivative is the derivative of the second derivative, the fourth derivative is the derivative of the third, and so on.

Summary: Your TI-83 or TI-84 **can't differentiate in symbols, but it can find the derivative at any point by using a numerical process**.

In calculus, a branch of mathematics, the third derivative is **the rate at which the second derivative, or the rate of change of the rate of change, is changing**. The third derivative of a function can be denoted by. Other notations can be used, but the above are the most common.

This is exactly what happens with power functions of e: the natural log of e is 1, and consequently, the derivative of ex is **ex** .

The derivative of zero is **zero**. This makes sense because it is a constant function.

**Derivatives as dy/dx**

- Add Δx. When x increases by Δx, then y increases by Δy : y + Δy = f(x + Δx)
- Subtract the Two Formulas. From: y + Δy = f(x + Δx) Subtract: y = f(x) To Get: y + Δy − y = f(x + Δx) − f(x) Simplify: Δy = f(x + Δx) − f(x)
- Rate of Change.

The first derivative is found by the formula **f′(x)=limh→0f(x+h)−f(x)h** f ′ ( x ) = lim h → 0 f ( x + h ) − f ( x ) h when h is approaching 0.

The Derivative as a Function

For this, you need to **use the TI-89's "d) differentiate" function**. The syntax of the function is "d(function, variable)." For example, if y = x^{3} - 2x + 4, the derivative of y with respect to x can be found as in the screen shot at right.

The "Second Derivative" is the derivative of the derivative of a function. So: Find the derivative of a function.

Example: A bike race!

The derivative at a point

The derivative of a function f(x) at a point (a,f(a)) is written as f′(a) and is defined as **a limit**.

The three basic derivatives (D) are: (1) for algebraic functions, D(x^{n}) = nx^{n}^{−}^{1}, in which n is any real number; (2) for trigonometric functions, D(sin x) = cos x and D(cos x) = −sin x; and (3) for exponential functions, D(e^{x}) = e^{x}.

Mechanical Features:

(i) **A traction motor must be robust and capable to withstand continuous vibrations** since service conditions are extremely severe. (ii) The weight of the traction motor should be minimum in order to increase the payload capacity of the vehicle.

Disadvantages of Electrical Drive**The application of the drive is limited because it cannot use in a place where the power supply is not available**. It can cause noise pollution. The initial cost of the system is high. It has a poor dynamic response.

MATLAB^{®} is a programming platform designed specifically for engineers and scientists **to analyze and design systems and products that transform our world**. The heart of MATLAB is the MATLAB language, a matrix-based language allowing the most natural expression of computational mathematics.

I had very good experience in MathWorks.**Job Security, good pay, Good work environment, Healthy competition**. Cultural events were good. Most enjoyable part was office parties and team lunch. Every day there was something to learn in Office.

Behaviors and actions: **Personality not only influences how we move and respond in our environment, but it also causes us to act in certain ways**. Multiple expressions: Personality is displayed in more than just behavior. It can also be seen in our thoughts, feelings, close relationships, and other social interactions.

MathWorks is **an American privately held corporation** that specializes in mathematical computing software. Its major products include MATLAB and Simulink, which support data analysis and simulation.

Introduction: By electric traction is meant **locomotion in which the driving (or tractive) force is obtained from electric motors**. It is used in electric trains, tramcars, trolley buses and diesel-electric vehicles etc.
