20 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Domain
- The set of permitted inputs for a function, determined by its definition and any stated contextual restrictions.
- Composition
- Applying one function to the result of another, with input restrictions checked at both stages of the calculation.
- Discriminant
- The quantity b squared minus four ac that determines the real-root pattern of a quadratic equation.
- Arithmetic sequence
- A sequence in which each term differs from the preceding term by the same fixed additive amount.
- Geometric sequence
- A sequence in which each term is obtained by multiplying its predecessor by a fixed common ratio.
- Limit
- The value approached by a function as its input approaches a specified point, whether or not that point is included.
- Derivative
- An instantaneous rate of change, represented geometrically by the tangent slope when the derivative exists at the point.
- Critical point
- An allowed input where a derivative vanishes or fails to exist, considered as a possible extremum location.
- Antiderivative
- A function whose derivative equals the given integrand, with different antiderivatives differing by a constant on an interval.
- Definite integral
- Signed accumulation over a specified interval, evaluated by an appropriate integration method with the bounds in their stated order.
- Dot product
- The sum of products of corresponding vector components, relating two vectors to the cosine of their included angle.
- Vector magnitude
- The nonnegative length of a vector, computed from its components using the appropriate Euclidean distance formula.
- Radian
- An angle measure defined by arc length divided by radius, used in standard trigonometric differentiation formulas.
- Coordinate shift
- A translation that changes a figure’s position while preserving its shape, with signs interpreted from the equation.
- Projection
- The component of a vector along a specified direction, distinct from the magnitude of the entire vector.
- Conditional probability
- The probability of an event after restricting attention to a specified conditioning event with positive probability.
- Expected value
- The sum of each possible numerical outcome multiplied by its probability, describing long-run average behavior under the model.
- Variance
- Average squared deviation from the mean, using the population or sample definition appropriate to the stated calculation.
- Combination
- An unordered selection of objects, unlike a permutation in which different arrangements count as different outcomes.
- Weighted mean
- An average that multiplies each value or group mean by its relevant weight before dividing by total weight.
