Even Functions: cos(-t) = cos(t), sec(-t) = sec(t)
Odd Functions: sin(-t) = -sin(t), tan(-t) = -tan(t), csc(-t) = -csc(t), cot(-t) = -cot(t)
Example: A point P(x, y) is shown on the unit circle corresponding to a real number t. Find the values of the trigonometric functions at t.

Case Study on Repairs and Strengthening of Corrosion-Damaged Buildings
Introduction
Corrosion of reinforcement steel is one of the major causes of deterioration in reinforced concrete structures. It occurs due to the penetration of moisture, oxygen, chlorides, and carbon dioxide into concrete. Corrosion causes expansion of steel, leading to cracking, spalling, reduction in bond strength, and loss of load-carrying capacity. Proper repair and strengthening are necessary to restore structural safety
## 4. Modern Validation APIs (Constraint Validation API)
For advanced tracking and custom error messaging, JavaScript provides the **Constraint Validation API**. This API gives you deep programmatic control over HTML5 validation states.
### Key Properties & Methods
* **element.validity**: An object containing boolean properties describing the validity state of the input.
* validity.valueMissing: True if required but empty.
* validity.typeMismatch: True if the syntax doesn't match the
The **Browser Object Model (BOM)** is what allows JavaScript to talk to the browser about things *outside* the context of the page's actual content. While the DOM deals with the document (HTML, CSS), the BOM deals with everything else—tabs, windows, history, the address bar, and the user's device information.
Here is a comprehensive breakdown of everything BOM, from the window object to how the browser manages state with cookies.
## 1. Introduction to BOM
The BOM is a collection of objects provided
