How do you solve sin 18?
The value of sin 18 degrees can be calculated by constructing an angle of 18° with the x-axis, and then finding the coordinates of the corresponding point (0.9511, 0.309) on the unit circle. The value of sin 18° is equal to the y-coordinate (0.309). ∴ sin 18° = 0.309.
How do you calculate tan 12?
To find the value of tan 12 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 12° angle with the positive x-axis.
- The tan of 12 degrees equals the y-coordinate(0.2079) divided by x-coordinate(0.9781) of the point of intersection (0.9781, 0.2079) of unit circle and r.
How do you find sin 19?
Explanation: For sin 19 degrees, the angle 19° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 19° value = 0.3255681. . . Since the sine function is a periodic function, we can represent sin 19° as, sin 19 degrees = sin(19° + n × 360°), n ∈ Z.
How do you find the value of sin 25?
The value of sin 25 degrees can be calculated by constructing an angle of 25° with the x-axis, and then finding the coordinates of the corresponding point (0.9063, 0.4226) on the unit circle. The value of sin 25° is equal to the y-coordinate (0.4226). ∴ sin 25° = 0.4226.
