Here since tan is negative in II quadrant, we put negative sign, Now Trigonometric table for 120 to 180 is given by,$\sin (120) = \sin (180 -60) =\sin 60= \frac {\sqrt {3}}{2}$,$\cos (120) = \cos (180 -60) =- \cos 60= – \frac {1}{2}$,$\tan 120 = \frac {\sin 120}{\cos 120} = -\sqrt {3}$,$\sin (135) = \sin (180 -45) = \sin 45= \frac {1}{\sqrt {2}}$,$\cos (135) = \cos (180 -45) =- \cos 45= -\frac {1}{\sqrt {2}}$,$\tan 135 = \frac {\sin 135}{ \cos 135} = -1$,$\tan 180 = \frac {\sin 180}{\cos 180} = 0$,$\csc 120 = \frac {1}{\sin 120} = \frac {2}{\sqrt 3}$,$\cot 120 = \frac {1}{\tan 120} = – \frac {1}{\sqrt 3}$,$\csc 135 = \frac {1}{\sin 135} = \sqrt 2$,$\sec 135 = \frac {1}{\cos 135} = -\sqrt 2$, Now Trigonometric table for 210 to 270 is given by,$\sin (210) = \sin (180 +30) =- \sin 30= -\frac {1}{2}$,$\cos (210) = \cos (180 +30) =- \cos 30=-\frac {\sqrt {3}}{2}$,$\tan (210) = \frac {\sin 210}{ \cos 210} = \frac {1}{\sqrt {3}}$,$\sin (225) = \sin (180 +45) =- \sin 45= -\frac {1}{\sqrt {2}}$,$\cos (225) = \cos (180+45) =- \cos 45= -\frac {1}{\sqrt {2}}$,$\tan 225 = \frac {\sin 225}{\cos 225} = 1$,$\sin (270) = \sin (180 +90) =- \sin 90= -1$,$\cos (270) = \cos (180+90) =- \cos 90= 0$,$\tan 270 = \frac {\sin 270}{\cos 270} = -\frac {1}{0}$Undefined value,$\csc (210) = \frac {1}{\sin (210)} = -2$,$\sec (210) = \frac {1}{\cos (210)}=-\frac {2}{\sqrt 3}$,$\cot (210) = \frac {1}{\tan (210)} = \sqrt {3}$,$\csc (225) = \frac {1}{\sin 225}= -\sqrt {2}$,$\sec (225) = \frac {1}{\cos 225}= -\sqrt {2}$, Now Trigonometric table for 300 to 360 is given by,$\sin (300) = \sin (360 -60) =- \sin 60=-\frac {\sqrt {3}}{2}$,$\cos (300) = \cos (360-60) =\cos 60=\frac {1}{2}$,$\tan (300) = \frac {\sin 300}{\cos 300} = -{\sqrt {3}}$,$\sin (315) = \sin (360 -45) =- \sin 45= -\frac {1}{\sqrt {2}}$,$\cos (315) = \cos (360-45) =\cos 45= \frac {1}{\sqrt {2}}$,$\tan 315 = \frac {\sin 315}{ \cos 315} =- 1$,$\tan (360) = \frac {\sin 360}{\cos 360} = 0$,$\csc (300) = \frac {1}{\sin (300)}=-\frac {2}{\sqrt 3}$,$\cot (300) = \frac {1}{\tan 300} = -\frac {1}{\sqrt {3}}$, How to calculate the trigonometric ratios of negative of the angle from 0 to 360, This is quite simple.Just remember this single thing,$\cos( x) = \cos (-x)$and$\sec(x) = \sec(-x)$,$\sin (x) = – \sin(-x)$,$\csc (x) = – \csc (-x)$,$\tan (x) = – \tan (-x)$,$\cot (x) = – \cot(-x)$,$\cos (-120) = \cos (120) = \cos (180 -60) =- \cos 60 = -\frac {1}{2}$,$\sin (-120)= – \sin(120) = – \sin 60 = – \frac {\sqrt {3}}{2}$, We have explained everything is terms of degrees, same thing can be done in radian form also. (ii) Take the remainder. A Computer Science portal for geeks. Cos(60) = -0.95241 assuming that angles are measured in radians, as would be done by most mathematicians. Â°), sin and csc are positive and other trigonometric ratios are negative. Image will be added soon. In the trigonometric functions sin θ, cos θ, tan θ, csc θ, sec θ and cot θ, if the angle θ is greater than or equal to 360°, we have to do the following steps. Sin 360 Degree. Hence, cos α = b / h. Now, for finding the value of cos 60 degrees, consider an equilateral triangle ABC as shown below. Open Live Script. For cos For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90° Cos is the opposite of sin.
