FAQs on Sin 45 Degrees Sin 45 degrees is the value of sine trigonometric function for an angle equal to 45 degrees. The value of sin 45° is 1/√2 or 0.7071 (approx).
How do you find cot 45?
To find the value of cot 45 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 45° angle with the positive x-axis.
- The cot of 45 degrees equals the x-coordinate(0.7071) divided by y-coordinate(0.7071) of the point of intersection (0.7071, 0.7071) of unit circle and r.
How do you solve sin 45 degrees?
The value of sin 45 degrees can be calculated by constructing an angle of 45° with the x-axis, and then finding the coordinates of the corresponding point (0.7071, 0.7071) on the unit circle. The value of sin 45° is equal to the y-coordinate (0.7071). ∴ sin 45° = 0.7071.
