Present Continuous

Actions that are happening now.

• Add -ing to the verb (e.g., I am talking, he/she/it is eating, you/we/they are talking).

Present Simple

Actions that happen regularly or habitually.

• For I, you, we, and they, use the base form of the verb (e.g., talk, eats, learn).
• For he, she, and it, add -s to the verb (e.g., talks, eats, learns).
• For questions, use do/does and do not add -s (e.g., Do you talk?, Does he eat?).
• For negatives, do not add -s (e.g., I don't talk, he doesn't learn).
• Use time expressions (e.g., always, usually, often, sometimes) before the verb.

Present Perfect

Past actions that have relevance to the present.

• For I, you, we, and they, add have.
• For he, she, and it, add has.
• Affirmative: I have (I've) talked to Peter, they have

Focal Length: Understanding Wide-Angle, Medium, and Telephoto Lenses

1. Wide-Angle Lenses

Wide-angle lenses capture a wider field of view, but they can distort straight lines near the edges of the frame, making them appear curved outward. Additionally, wide-angle lenses exaggerate depth, making objects in the foreground appear larger and those in the distance appear farther away. As a result, when figures move toward or away from the camera, a wide-angle lens makes them seem to cover ground more rapidly.

2. Medium Lenses

Medium lenses, typically around 50mm in length, aim to avoid noticeable perspective distortion. With a medium lens, horizontal and vertical lines are rendered as straight and perpendicular.

3. Telephoto Lenses

Telephoto lenses have... Continue reading "Understanding Focal Length: Wide-Angle, Medium, and Telephoto Lenses" »

Types of Map Projections by Preserved Dimension

1. Equidistant Projections
These projections preserve distances along specific directions, typically along straight lines known as automecoic lines. Linear deformation occurs in other directions. The linear anamorphosis, calculated as the ratio of the projected distance to the true distance, equals 1 along automecoic lines. Equidistant projections are useful for measuring distances from a central point.
2. Conformal Projections
These projections preserve angles between intersecting curves and lines. The angular anamorphosis represents the difference between the angle on the sphere and the corresponding angle on the map. Conformal projections are commonly used for nautical charts, often employing parallel... Continue reading "Map Projections: Dimensions, Geometry, and Classifications" »

Tangencies

Making Tangents

Two Circles

• External Tangents: Draw another circle concentric to the larger one with radius R - r. Join the centers. This is the bisector. Draw an auxiliary circle to the centers. Join the center with the points of intersection with the smaller circumference and extend. Where the lines intersect the larger circle will be the tangent points. Parallels are drawn to the smaller circle to find all points of contact.
• Internal Tangents: The process is the same, except that the circle is of radius R + r, and the parallels are drawn to the opposite side.

Tangent to a Circle Passing Through Point P

• If the tangent is to be external, a concentric circle of radius R + r is drawn. From P, an arc of radius R is drawn, which intersects

Audio Visual Q1: Color Theory

Color Description

• Chroma: How pure a hue is in relation to gray.
• Saturation: The degree of purity of a hue.
• Intensity: The lightness or dullness of a hue (adding black or white).
• Value: A measure of the amount of light reflected from a hue.
• Shade: Produced by the addition of black.
• Tint: Produced by the addition of white.

Color Systems

• Subtractive Color: Used when mixing colors with paint. Begins with white and ends with black (CMYK).
• Additive Color: Used on computers. Begins with black and ends with white (RGB).

The Color Wheel

• Primary Colors: The basic essence; these colors cannot be created by mixing others.
• Secondary Colors: Colors achieved by mixing two primary colors.
• Tertiary Colors: Achieved by mixing primary and secondary

The Point

A circle and a line are tangent if they intersect at exactly one point. Two circles are tangent if the line joining their centers is tangent to both. An oval is a closed curve formed by arcs of circles and symmetrical about two perpendicular axes. A ball is a closed curve composed of arcs symmetric about one axis.

Graphical Representation of the Point

Graphically, the point is the minimal footprint of a graphical tool. Geometrically, it is the intersection of two lines. The point can take several forms depending on the instrument used to create it: oval, star, round, polygonal, etc.

Sensory Perception of the Point

• Single Point: Located in the center of a bracket or blade, it creates a sense of order or balance. Located at one end, it creates
