…
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 value of sin 75 degrees in fraction?

How do you find the value of sin 50 degrees?
⇒ 50 degrees = 50° × (π/180°) rad = 5π/18 or 0.8726 . . . Explanation: For sin 50 degrees, the angle 50° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 50° value = 0.7660444. . .
How do you find the value of sin 25?
The value of sin 25° is equal to the y-coordinate (0.4226). ∴ sin 25° = 0.4226.
How do you find sin 75 without a calculator?
sin 75°: Now using the formula for the sine of the sum of 2 angles, sin(A + B) = sin A cos B + cos A sin B, we can find the sine of (45° + 30°) to give sine of 75 degrees.
How do you find the exact value of cos 75?
How do you find the value of sin 72?
The value of sin 72 degrees can be calculated by constructing an angle of 72° with the x-axis, and then finding the coordinates of the corresponding point (0.309, 0.9511) on the unit circle. The value of sin 72° is equal to the y-coordinate (0.9511). ∴ sin 72° = 0.9511.
