In this lesson, I will teach you how to obtain the trigonometric ratios of 0º (and 360º), 30º, 45º, 60º, 90º, 180º and 270º without using the calculator. Finding the cosecant of the 30-degree angle, we see the hypotenuse is 2 and the side opposite the 30-degree angle is 1, so csc 30 = 2/1 = 2. So, it is mathematically written as $\csc{\Big(\dfrac{\pi}{6}\Big)}$ in trigonometric mathematics. tan x = sin x cos x . Cosecant is a function that has a very close relationship with the sine function. Given csc theta = 1.404 . sin is negative in quandrants III and IV, so your answers will be in those quadrants. The ordered pairs (x,y) can be viewed as (cos,sin). The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle, which is the circle of radius one centered at the origin O of this coordinate system. The cosecant of angle thirty degrees in Sexagesimal system is written as $\csc{(30^°)}$ or $\operatorname{cosec}{(30^°)}$. As with all trigonometric functions, cosecant is based on a right triangle.
