Réponse

Function from ℕ to ℝ representing a list of numbers.

2Question

Sequence types — examples?

Réponse

Arithmetic and geometric sequences.

3Question

Arithmetic sequence — fixed?

Réponse

Constant difference between consecutive terms.

4Question

Geometric sequence — fixed?

Réponse

Constant ratio between consecutive terms.

5Question

Sequence convergence — condition?

Réponse

Monotone and bounded sequences converge.

6Question

Limit of a sequence — when?

Réponse

Terms approach a finite value as n→∞.

7Question

Parametric curve — role?

Réponse

Represented by vector functions depending on a parameter.

8Question

Position vector — in curves?

Réponse

Assigns a point on the curve for each parameter.

9Question

Derivative vector — represents?

Réponse

Instantaneous velocity in a curve.

10Question

Nuage de points — purpose?

Réponse

Visualize data distribution in statistics.

11Question

Affine fit — purpose?

Réponse

Finds the best linear approximation to data points.

12Question

Cross product — in space?

Réponse

Produces a vector orthogonal to two vectors.

13Question

Vector cross product — properties?

Réponse

Anticommutative and orthogonal to original vectors.

14Question

Random variable — definition?

Réponse

Function from a probability space to ℝ.

15Question

Uniform probability — meaning?

Réponse

Equal likelihood for all elementary outcomes.

16Question

Left derivative — in?

Réponse

Limit approaching from the left side of a point.

17Question

Right derivative — in?

Réponse

Limit approaching from the right side of a point.

18Question

Primitive function — role?

Réponse

Function whose derivative equals the original function.

19Question

Réponse

First-order linear homogeneous: y' – m y = 0.

20Question

Solution to y' – my=0?

Réponse

y = C e^{m x}.

Réponse

Left and right derivatives equal at a point.

24Question

Vector derivative — interpretation?

Réponse

Represents velocity and acceleration.
