The reciprocal of the tangent ratio is known as cotangent ratio of an angle, abbreviated as "cot". See also: sine and cosine. Names of standardized tests are owned by the trademark holders and are not affiliated with Varsity Tutors LLC.

Note: The U shapes of the cosecant graph are tangent to its reciprocal function, sine, at sine's max and min locations. Note: the U shapes of the secant graph are tangent to its reciprocal function, cosine, at cosine's max and min locations.
When hand-drawing the trigonometric graphs, draw vertical dotted lines at intervals to remind you of the connection to the four quadrants from the unit circle and to keep your graphs accurate.
Example 1: Determine the period, phase shift, and the location of the asymptotes for the function. Because the phase shift is positive, it is to the left Figure 5. Figure 5 Phase shift of the tangent function. The amplitude is not defined for the secant or cosecant. Example 2: Determine the period, phase shift, and the location of the asymptotes for the function. Graphing the sine or cosine can make it easier to graph the cosecant or secant. Several periods of the cosecant function and the sine function.
