- 6. The length of a vector.
- 7. A formula useful for finding powers and roots of complex numbers.
- 8. The branch of mathematics dealing with limits, derivatives, definite integrals, indefinite integrals, and power series.
- 9. Angle-angle similarity. When two triangles have corresponding angles that are congruent as shown below, the triangles are similar.
- 10. A way of representing gambling payoffs of an event by a method similar to odds against. If the gambling odds are m:n (read aloud "m to n"), then a bet of n dollars pays m dollars profit if the bettor wins.
Down
- 1. The process of solving a linear system of equations that has been transformed into row-echelon form or reduced row-echelon form. The last equation is solved first, then the next-to-last, etc.
- 2. When we say z is jointly proportional to a set of variables, it means that z is directly proportional to each variable taken one at a time.
- 3. Trig identities that show how to find the sine, cosine, or tangent of half a given angle.
- 4. One of the flat surfaces making up a polyhedron. Note: The faces of a polyhedron are all polygons.
- 5. A quadrilateral with two pairs of adjacent sides that are congruent. Note that the diagonals of a kite are perpendicular.
