Cos 150 degrees is the value of cosine trigonometric function for an angle equal to 150 degrees. The value of cos 150° is −√3/2 or -0.866 (approx) What is the Value of Cos 150 Degrees in …

To find the exact values of cos 150° and sin 150°, we will use the trigonometric identity cos (180° - Θ) and sin (180° - Θ). Answer: The exact value of cos (150 ∘) is −√3/2 and sin (150 ∘) is 1/2. …

2017年1月29日 · See explanation. First let's calculate sin(-150) sin(-150)=-sin150 we can write this, because sinx is an odd function. -sin150=-sin(180-30)=-sin30=-1/2 Now we can calculate …

Since sine function is positive in the second quadrant, thus sin 150° value = 1/2 or 0.5 Since the sine function is a periodic function, we can represent sin 150° as, sin 150 degrees = sin(150° + …

#sin(150^o)=sin(30^o)=1/2# #cos(150^o)=-cos(30^o)=-sqrt(3)/2# #tan(150^o)=frac{sin(150^o)}{cos(150^o)}=-1/sqrt(3)#

The value of cosec 150 degrees can be calculated by constructing an angle of 150° with the x-axis, and then finding the coordinates of the corresponding point (-0.866, 0.5) on the unit …

2015年7月13日 · sin -150= -sin150= -sin(180-30)= -sin30= -1/2. cos -150= cos150= cos(180-30)= -cos30= -sqrt3/2. tan -150= -tan 150= -tan(180-30)= tan30= 1/sqrt3

The value of tan 150° is equal to the y-coordinate(0.5) divided by the x-coordinate (-0.866). ∴ tan 150° = -1/√3 or -0.5774. How to Find Tan 150° in Terms of Other Trigonometric Functions? …

2015年2月15日 · sec^2(300^o) = (1 / (cos^2(300^o))) cos(300^o) = cos(-60^o) = cos(60^o) = 1/2 cos^2(300^o) = 1/4 sec^2(300^o) = 4 cos(150^o) = - cos(30^o) = - sqrt(3)/2 cos^2(150^o ...

Answer: cos 0° = 1, cos 30° = √3/2, cos 45° = 1/√2, cos 60° = 1/2, cos 90° = 0, cos 120° = -1, cos 150° = -√3/2, cos 180° = -1, cos 270° = 0, cos 360° = 1. We will find the values of angles for …
