How do you find the value of sin 106?
Using trigonometric identities, we can write cos 106° in terms of sin 106° as, cos(106°) = -√(1 – sin²(106°)). Here, the value of sin 106° is equal to 0.9613.
How do you find sin 70 without a calculator?
How to Find the Value of Sin 70 Degrees? The value of sin 70 degrees can be calculated by constructing an angle of 70° with the x-axis, and then finding the coordinates of the corresponding point (0.342, 0.9397) on the unit circle. The value of sin 70° is equal to the y-coordinate (0.9397). ∴ sin 70° = 0.9397.
How do you find the value of sin 105?
The value of sin 105° is equal to the y-coordinate (0.9659). ∴ sin 105° = 0.9659.
How do you find the value of sin 74?
The sin of 74 degrees is 0.96126, the same as sin of 74 degrees in radians. To obtain 74 degrees in radian multiply 74° by π / 180° = 37/90 π. Sin 74degrees = sin (37/90 × π).
How do you solve sin 80?
The value of sin 80 degrees can be calculated by constructing an angle of 80° with the x-axis, and then finding the coordinates of the corresponding point (0.1736, 0.9848) on the unit circle. The value of sin 80° is equal to the y-coordinate (0.9848). ∴ sin 80° = 0.9848.
How do you find sin 21?
Using trigonometry formulas, we can represent the sin 21 degrees as: ± √(1-cos²(21°))…We can use trigonometric identities to represent sin 21° as,
- sin(180° – 21°) = sin 159°
- -sin(180° + 21°) = -sin 201°
- cos(90° – 21°) = cos 69°
- -cos(90° + 21°) = -cos 111°
How do you calculate sin F?
