Essential Numerical Methods with C Examples

Essential Numerical Methods with C Examples

1. Newton-Raphson (Nonlinear Equation)

Algorithm (Very Simple Version)

  1. Read starting guess (x)
  2. Read tolerance (how small the error should be)
  3. Repeat many times:
    1. Calculate function value f(x)
    2. Calculate slope f'(x)
    3. If slope is almost zero → stop (bad)
    4. New x = x − f(x) / f'(x)
    5. If change is very small → stop (found answer)
  4. Show the root

C

#include <stdio.h>
#include <math.h>

double f(double x){ return x*x*x - 2*x - 5; }
double df(double x){ return 3*

PGP Compression, Steganography & Network Security Tools

PGP Compression (Ultra-Compact Answer)

PGP performs compression before encryption to reduce message size and improve security. Compression removes redundancy so encrypted output becomes smaller, faster to transmit, and harder to analyze because repeated patterns disappear. The most commonly used algorithm is ZIP (LZ77-based) inside PGP. The process is: Message → Compression → Encryption → Transmission → Decryption → Decompression. Compression helps hide patterns in plaintext, making cryptanalysis

Fundamental Concepts in Classical Mechanics Physics

Physical Quantities and Measurement

Physical Quantity: A property of a body or phenomenon that can be measured and expressed by a number and a unit (e.g., 5 m, 10 s, 3 kg). It allows us to describe physical laws quantitatively. A physical quantity is defined either by specifying how it is measured or by stating how it is calculated from other measurable quantities.

Unit of Measurement: A standard reference used for comparing quantities of the same kind. Example: meter (m) for length, second (s) for

Symbolic Capital in Hari Kunzru’s Deus Ex Machina

Symbolic Capital in Deus Ex Machina

In Hari Kunzru’s short story “Deus Ex Machina” (2005), critical attention often gravitates towards the narrator (a “Guardian Angel”), overlooking a subject more revealing from a cultural perspective: Christina. While the supernatural narrator frames the story, it is Christina’s journey that reflects the devastating pressure of the contemporary world. This essay argues that her actions are best understood not as romantic failures, but rather as the result of
