Across
- 3. A conic section that looks like a stretched circle, defined by points where the total distance from two fixed points (foci) is constant.
- 4. A rectangular array of numbers or objects arranged in rows and columns, used in linear algebra.
- 6. A number or expression that divides another number or expression evenly.
- 8. A relation where each input is connected to exactly one output.
- 12. The point where curves, edges, or lines meet; for conics, it’s a significant point of the shape.
- 13. Measures how a function changes as its input changes, representing its slope at any point.
- 14. A unit for measuring angles, defined by the angle at the center of a circle that an arc of the circle's radius creates.
- 16. A line that a graph gets closer to but never touches or crosses.
- 17. A quantity with both magnitude and direction, often shown as an arrow.
- 19. An expression with variables and coefficients, involving only addition, subtraction, multiplication, and non-negative integer exponents.
- 20. The inverse of exponentiation, showing the power to which a base number is raised to get a certain number.
Down
- 1. Function A function defined by a polynomial equation with terms of varying powers of the variable.
- 2. A polynomial with two terms.
- 5. A trigonometric function that is the ratio of the opposite side to the adjacent side of a right triangle.
- 7. Shapes formed by cutting a cone with a plane, including ellipses, parabolas, and hyperbolas.
- 9. Represents the area under a curve or the accumulation of quantities.
- 10. A trigonometric function that is the reciprocal of the cosine function.
- 11. A value that makes a function equal to zero, also known as a root.
- 15. A conic section formed when a plane cuts both halves of a cone, creating two symmetrical open curves.
- 18. A conic section formed by cutting a cone parallel to its side, defined by points equidistant from a focus and a directrix.
