What is sin 270 plus theta?
Therefore, sin (270° + θ) = – cos θ, (since sin (90° + θ) = cos θ) cos (270° + θ) = cos (1800 + 90° + θ)
What is the value of sin 270 theta?
-1 Hence, the sine of 270 degrees is -1. We know the trigonometric identity cos(270∘+θ)=sinθ. Hence, the cosine of 270 degrees is 0.
How do you find sin 270 degrees?
The value of sin 270 degrees is -1….We can use trigonometric identities to represent sin 270° as,
- sin(180° – 270°) = sin(-90°)
- -sin(180° + 270°) = -sin 450°
- cos(90° – 270°) = cos(-180°)
- -cos(90° + 270°) = -cos 360°
What is the exact value of cos 270 degrees?
0 270° lies in 3rd Quadrant. So the exact value of cos 270 is 0 .
Why is sin 270 degrees?
The value of sin 270 degrees can be calculated by constructing an angle of 270° with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of sin 270° is equal to the y-coordinate (-1). ∴ sin 270° = -1.
What is the value of cosine at 270?
0 The value of cos 270° is equal to the x-coordinate (0). ∴ cos 270° = 0.
What is the exact value of cos 270?
0 270° lies in 3rd Quadrant. So the exact value of cos 270 is 0 .
