Trigonometric Functions Crossword Puzzle

QUESTIONS LIST: cosecant : the ratio of the hypotenuse (in a right-angled triangle) to the side opposite an acute angle; the reciprocal of sine, secant : the ratio of the hypotenuse to the shorter side adjacent to an acute angle (in a right-angled triangle); the reciprocal of a cosine, sine : the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse, unite circle : the circle whose center is at the origin and whose radius is one, cosine : the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse, reference angle : the positive acute angle formed between the terminal side of an angle and the x-axis, cotangent : (in a right-angled triangle) the ratio of the side (other than the hypotenuse) adjacent to a particular acute angle to the side opposite the angle, function : an operation that assigns a correspondence from elements of one set to elements of another set, tangent : the trigonometric function that is equal to the ratio of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right triangle, rule : the part of a function that dictates the exact correspondence between the elements of one set and the elements of another set.
