  1. 5. A relation in which each input has exactly one output
  2. 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
  3. 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
  4. 11. the total distance around the outside boundary of a two-dimensional shape, calculated by adding up the lengths of all its sides
  5. 12. the measure of a line's steepness and direction
  6. 14. a rational function is any function that can be expressed as the ratio (or fraction) of two
  7. 17. a whole number that divides another number exactly
  8. 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)

  1. 1. functions of an angle that relate an angle in a right triangle to the ratio of its side lengths
  2. 2. a quantity with both magnitude (size/length) and direction
  3. 3. a mathematical formula that relates the lengths of the sides of any triangle to the cosine of one of its angles
  4. 4. a value that, when multiplied by itself, results in the original number, essentially "undoing" the squaring operation
  5. 6. The set of all possible output values of a function
  6. 8. An inverse function "undoes" the original function
  7. 10. a symmetrical U-shaped curve
  8. 13. involving the second and no higher power of an unknown quantity or variable
  9. 15. the measurement of the space inside a flat
  10. 16. the point where a line or curve crosses an axis on a graph
