Across 1. A function with a graph that is symmetric with respect to the origin. (2 Words) 6. A line that touches a curve at a point without crossing over. (2 Words) 8. A line or curve that the graph of a relation approaches more and more closely the further the graph is followed. 10. The set of all real numbers between two given numbers. 11. The branch of mathematics that treats the measurement of and relationships between the sides and angles of plane triangles and the solid figures derived from them. 14. A function which gives the slope of a curve; that is, the slope of the line tangent to a function. 16. A line perpendicular to a tangent line. (2 Words) 17. A unit of angle measure equal to of a complete revolution. 19. The process of finding a derivative. 20. It is the ratio of the length of the side opposite that angle to the length of the hypotenuse or x/r. (2 Words) 21. Angles which, drawn in standard position, share a terminal side. 25. A point at which the graph of a relation or function is not connected. 26. A word used to indicate any path, whether actually curved or straight, closed or open. 28.

The smallest angle that the terminal side of a given angle makes with the x-axis. (2 Words) 15. A test use to determine if a relation is a function. (3 Words) 18. It is used to determine if a function has an inverse that is also a function. (3 Words) 22. The graphs of sine and cosine are the same when sine is shifted left by pi/2. (2 Words) 23. It is the angle made at the center of a circle by an arc whose length is equal to the radius of the circle. (2 Words) 24. It is a set of ordered pairs in which each x-element have only one y-element associated with it. 27. A "number" which indicates a quantity, size, or magnitude that is larger than any real number. 29.

It is formed by two rays with a common endpoint composed of an initial side (positive x axis), terminal side and vertex. 38. The value that a function or expression approaches as the domain variable(s) approach a specific value.
