Reciprocal identity of sine; undefined where sine is zero, resulting in vertical asymptotes on its graph. Secant
Reciprocal identity of cosine; undefined where cosine is zero, leading to vertical asymptotes on its graph. Reciprocal Identity
Relationship where one trigonometric function equals 1 divided by another, forming secant and cosecant from cosine and sine. Asymptote
Vertical line on a graph where a function approaches infinity or is undefined, often at zeros of sine or cosine. Period
Horizontal length required for a trigonometric graph to complete one full cycle, calculated as 2π divided by the frequency. Transformation
Modification of a graph's shape or position, including stretches and shifts, applied to trigonometric functions. Peak
Maximum point on a trigonometric graph, corresponding to highest values of sine or cosine and their reciprocals. Valley
Minimum point on a trigonometric graph, corresponding to lowest values of sine or cosine and their reciprocals. Undefined Value
Point where a function cannot be evaluated, often due to division by zero, resulting in asymptotes. Smiley Face
Upward-opening curve segment between asymptotes on secant or cosecant graphs, reflecting positive reciprocal values. Frowny Face
Downward-opening curve segment between asymptotes on secant or cosecant graphs, reflecting negative reciprocal values. Cycle
Complete repetition of a trigonometric graph's pattern, marked by recurring peaks, valleys, and asymptotes. Frequency
Number indicating how many cycles a trigonometric function completes in a given interval, affecting the period. Stretch
Transformation that alters the amplitude or period of a trigonometric graph, making it taller or wider. Shift
Transformation that moves a trigonometric graph horizontally or vertically without changing its shape.
