Analysis means breaking something complex into smaller parts to understand it better, identify patterns, find causes, or make decisions.
It’s used in many fields — business, science, engineering, literature, etc.
In simple terms:
Analysis = Understanding something deeply by examining its components.
Focus: Descriptive & non-numerical data.
Goal: Understand qualities, meanings, and patterns.
Examples:

Convolutional Neural Networks, or CNNs, are a special class of deep learning models designed primarily for analyzing visual data such as images and videos. Unlike traditional fully connected neural networks, CNNs are built to automatically and adaptively learn spatial hierarchies of features through convolution operations. The main components of a CNN include convolutional layers, activation layers, pooling layers, and fully connected layers. The convolutional layer applies small filters (also called

It is a strategic business tool introduced by Michael Porter.
It helps a company analyze its internal activities to see how it creates value for its customers.
The "value" is the amount customers are willing to pay for a product or service.
The goal is to identify activities where the company can reduce costs or add more value (differentiation) to gain a competitive advantage.
The model splits a company's activities into two categories: Primary Activities
EDEMA: o edema é o acúmulo de líquido nos tecidos do corpo, causando inchaço.
CAUSAS: A formação de edema está relacionada ao desequilíbrio das forças que regulam o fluxo de fluidos nos capilares sanguíneos. As principais causas são
Aumento da pressão hidrostática: A pressão que o sangue exerce nas paredes dos vasos aumenta, forçando o líquido para fora. Pode ocorrer devido a: Insuficiência cardíaca congestiva, que causa um acúmulo de sangue e um aumento da pressão nas veias.

Interest in the 10th year: simple vs. compound (7% on $2,800)
Simple: yearly interest = 2800×0.07=1962800\times0.07=1962800×0.
