Polynomials:
- Operations involve addition, subtraction, multiplication, and division.
- Factoring involves breaking down polynomials into simpler expressions.
- The Remainder and Factor Theorems relate factors and remainders when polynomials are divided.
Functions:
- Linear functions have a constant rate of change, represented by a straight line.
- Quadratic functions have a parabolic graph.
- Polynomial functions involve higher powers of the variable.
- Exponential functions exhibit exponential growth or decay.
- Transformations can shift, stretch, compress, or reflect graphs.
- Inverse functions "undo" the original function.
Complex Numbers:
- They involve the imaginary unit 'i', where i² = -1.
- Operations include addition, subtraction, multiplication, and division.
- Polar form represents complex numbers using magnitude and angle.

Trigonometric Ratios:
- Sine (sin), cosine (cos), and tangent (tan) are ratios of sides in right triangles.
- They are used to solve for unknown angles and side lengths.
Unit Circle:
- A circle with a radius of 1 used to represent trigonometric values.
- Radians and degrees measure angles on the unit circle.
- Key values of sine and cosine are memorized for specific angles.
Trigonometric Identities:
- Pythagorean identities relate sine, cosine, and tangent.
- Reciprocal identities show relationships between trigonometric functions.
- Angle sum and difference formulas provide relationships between trigonometric functions of different angles.

Conic Sections:
- Parabolas are U-shaped curves formed by intersecting a cone with a plane.
- Ellipses are oval-shaped curves formed by intersecting a cone with a plane.
- Hyperbolas consist of two separate curves, formed by intersecting a cone with a plane.
- Each has its own unique equation and properties.
Coordinate Geometry:
- The slope of a line measures its steepness.
- Distance formula calculates the distance between two points.
- Midpoint formula finds the middle point between two points.
- Equations of lines can be expressed in various forms (slope-intercept, point-slope, standard).
Transformations:
- Rigid transformations preserve size and shape, including:
  - Translations (shifting a figure)
  - Rotations (turning a figure)
  - Reflections (flipping a figure)
- Non-rigid transformations change size or shape like Dilations (enlarging or shrinking a figure).

Probability:
- Basic concepts include events, sample space, and probability of events.
- Independent events occur without affecting each other's probabilities.
- Dependent events have probabilities influenced by previous events.
- Permutations refer to orderings of objects, while combinations refer to selections without order.
Statistics:
- Measures of central tendency represent typical values in a dataset:
  - Mean (average)
  - Median (middle value)
  - Mode (most frequent value)
- Measures of variability describe data spread:
  - Range (difference between highest and lowest)
  - Variance (average squared deviation)
  - Standard deviation (square root of variance)
- Data analysis includes interpreting statistics to draw conclusions

Limits:
- The concept of approaching a value without necessarily reaching it.
- Basic calculations involve finding the limit of a function as an input value approaches a specific point.
Derivatives:
- Represent instantaneous rates of change.
- Basic rules include the power rule, product rule, and quotient rule.
Integrals:
- Represent area under a curve.
- The concept provides a foundation for solving problems involving accumulation.
