Comprehensive Review Notes
Filipino
- Idyolek: Unique, personal language use. Each person has a distinct style. (e.g., Noli De Castro's "Magandang Gabi Bayan")
- Dayalek: Language varies by region. (e.g., Tagalog "Bakit?" vs. Batangas "Bakit ga?")
- Sosyolek: Temporary variety used by a particular group, related to socioeconomic status or gender.
- Etnolek: Develops from ethno-linguistic groups.
- Ekolek: Language used at home.
- Pidgin: Makeshift language with no formal structure used between speakers of different languages.
- Creole: Pidgin language that develops a formal structure and becomes a primary language.
- Rejister: Specialized language in a specific domain.
- Jargon: Special words/expressions used by a professional group.
English Speech Styles
- Frozen: Very formal, fixed language (anthems, pledges).
- Formal: Used in large groups, avoids slang (speeches, meetings).
- Consultative: Semi-formal, two-way participation (teacher-student).
- Casual: Relaxed, slang common (friends, family).
- Intimate: Private language (close friends, family).
Purpose of Speech
- Inform, Motivate/Persuade, or Entertain.
- Specific Purpose Statement: What the speaker will accomplish.
- Kinesics: Body motion communication/body language.
Philo
- Maslow's Hierarchy of Needs:
- Physiological
- Safety
- Love and belonging
- Esteem
- Self-actualization
- Needs lower in the hierarchy must be met first.
- Self-esteem: Self-respect.
- Self Concept: Beliefs about oneself.
- Self Confidence: Trust in one's abilities.
Science
- Nuclear Fission: Heavy nucleus splits into two with energy release and neutron emission.
- Nuclear Fusion: Light atoms smash together to produce energy.
- Convergence Theory: Industrialized nations develop similar societal patterns, creating a global culture.
- Convergent Plate: Plates moving towards each other, forming mountains or subduction zones.
- Dimitri Mendeleev: Developed periodic table in 1869.
- Mohs Scale: Measures mineral hardness (Talc = 1, Diamond = 10).
- Hermaphrodite: Organism with male and female reproductive organs.
- Cuneiform: Sumerians' earliest writing system.
- Ziggurat: Sumerian step pyramid.
Layers of Earth
- Crust: Thinnest layer, continental and oceanic types.
- Mantle: Thickest layer, constant motion, convective circulation.
- Core:
- Inner core: Extreme temperature/pressure, solidifying.
- Outer core: Liquid, violent convection, creates Earth’s magnetic field.
- Universe age: 13.8 billion years.
- Atom: Smallest unit of matter.
- Dalton’s Atomic Theory: All matter made of indivisible atoms.
- Gas Giants: Jupiter, Saturn, Uranus, Neptune.
Light Rays
- Light Ray: Direction of light propagation.
- Geometrical Optics: Rules for light ray paths. In uniform medium, rays travel in straight lines.
Reflection, Refraction, Diffraction
- Reflection: Waves bounce off a barrier; angle of incidence equals angle of reflection.
- Refraction: Waves change direction/speed as they pass from one medium to another.
- Diffraction: Waves bend around obstacles/openings.
Relativity Theory
- Einstein: Laws of physics are the same for all non-accelerating observers; speed of light is constant.
Periodic Table
- Elements arranged by atomic number.
- Metals: Left side, lustrous, conductive, lose electrons.
- Metalloids: Zig-zag line, properties of both metals and nonmetals, semiconductors.
- Nonmetals: Right side, poor conductors, gain electrons.
- Groups: Columns, similar valence electrons.
- Periods: Rows, same highest electron energy level.
Chemical Bonding
- Ionic Bonds: Between atoms with different electronegativity, metals and nonmetals.
- Covalent Bonds: Atoms share electrons, nonmetals.
- Metallic Bonds: Metals share valence electrons, electron sea.
Laws of Motion
- 1st Law (Inertia): Object at rest stays at rest, object in motion stays in motion unless acted upon by force.
- 2nd Law: F = ma (Force = mass x acceleration).
- 3rd Law: For every action, equal and opposite reaction.
Atoms
- Made of protons (+), neutrons (neutral), and electrons (-).
- Protons/neutrons in nucleus; electrons orbit nucleus.
- Electrons are fundamental particles.
Hubble's Theory
- Universe is expanding.
- Hubble's Law: v = H_0D (velocity = Hubble constant x distance).
- Einstein initially proposed a cosmological constant, later called it his "biggest blunder".
Other Definitions
- Crater: Cup-shaped depression.
- Complete flower: Has sepals, petals, pistils, and stamens.
- Wavelength: Distance between successive identical parts of a wave.
- Frequency: Number of waves passing a point per second.
Mechanical Wave Types
- Transverse: Particles move perpendicular to wave direction.
- Longitudinal: Particles move parallel to wave direction.
Electromagnetic Waves
- No medium needed; changes in electric/magnetic fields.
- Travel at the speed of light.
- Examples: Light, radio, thermal radiation.
Math
- Qualitative vs. Quantitative
- Mean, Median and Mode
- Function Operations:
- Given f(x) = 3x + 2 and g(x) = 4 – 5x
- (f + g)(x) = –2x + 6
- (f – g)(x) = 8x – 2
- (f × g)(x) = –15x^2 + 2x + 8
- (\frac{f}{g})(x) = \frac{3x+2}{4-5x}
- Function Notation:
- y = f(x)
- Find f(2) when f(x) = 3x
- Inverse Function if f(x) = y, the applying its inverse function g to y gives the result x, g(y) = x.
- Univariate and Bivariate Data
- Percentile: Value below which a given percentage falls.
Algebra Examples
- Sum of three consecutive multiples of seven is 168. Middle number is 56.
- Abigail is three years older than half of Susan’s age. In twelve years, Susan’s age will be seven more than three quarters of Abigail’s age. Abigail is currently 8 years old.
