Across
- 5. A relation in which each input has exactly one output
- 7. a variable is a symbol (usually a letter like \(x\), \(y\), or \(z\)) that represents an unknown number, a quantity that can change, or a placeholder for any member of a set
- 9. a fundamental trigonometric law stating that for any triangle, the ratio of the length of a side to the sine of its opposite angle is constant for all three sides
- 11. the total distance around the outside boundary of a two-dimensional shape, calculated by adding up the lengths of all its sides
- 12. the measure of a line's steepness and direction
- 14. a rational function is any function that can be expressed as the ratio (or fraction) of two
- 17. a whole number that divides another number exactly
- 18. the sum of the terms in a sequence, representing an addition of numbers or functions, which can be finite (ending) or infinite (continuing forever)
Down
- 1. functions of an angle that relate an angle in a right triangle to the ratio of its side lengths
- 2. a quantity with both magnitude (size/length) and direction
- 3. a mathematical formula that relates the lengths of the sides of any triangle to the cosine of one of its angles
- 4. a value that, when multiplied by itself, results in the original number, essentially "undoing" the squaring operation
- 6. The set of all possible output values of a function
- 8. An inverse function "undoes" the original function
- 10. a symmetrical U-shaped curve
- 13. involving the second and no higher power of an unknown quantity or variable
- 15. the measurement of the space inside a flat
- 16. the point where a line or curve crosses an axis on a graph
