WebOct 6, 2024 · In Figure 7.4.1, the cotangent of angle t is equal to cost sin t = x y, y ≠ 0. The cotangent function is abbreviated as cot. The cosecant function is the reciprocal of the sine function. In Figure 7.4.1, the cosecant of angle t is equal to 1 sin t = 1 y, y ≠ 0. The cosecant function is abbreviated as csc.
WebA unit circle is a circle of radius 1 centered at the origin. The right triangle definition of trigonometric functions allows for angles between 0° and 90° (0 and in radians). Using the unit circle definitions allows us to extend the domain of trigonometric functions to all real numbers. Refer to the figure below.
