From the value of sin 0, we will obtain the value of sin 180.
We know that the exact value of sin 0 degree is 0.
So, Sin 180 degree is +(sin 0) which is equal to +(0)
Therefore, the value of sin 180 degrees = 0.
The value of sin pi can be derived from some other trigonometric angles and functions like sine and cosine functions from the <a href="https://byjus.com/maths/trigonometry-table/">trigonometry table</a>.
It is known that,
180° – 0° = 180° ———– (1)
270° – 90° = 180°———— (2)
Sine 180 Degree Derivation: Method 1
Now we can use the above expression (1) in terms of sine functions
From the supplementary angle identity,
Sin A = Sin (180° – A )
Therefore,
Sin ( 180° – A ) = Sin A
Sin ( 180° – 0° ) = Sin 0°
Sin 180° = 0 [ Since the value Sin 0° is 0]
