Value of sin180 |
|
Answer» 0 0 0 0 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\xa0value 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\xa0trigonometry table.It is known that,180° – 0° = 180° ———– (1)270° – 90° = 180°———— (2)Sine 180 Degree Derivation: Method 1Now we can use the above expression (1) in terms of sine functionsFrom the supplementary angle identity,Sin A = Sin (180° – A )Therefore,Sin ( 180° – A ) = Sin ASin ( 180° – 0° ) = Sin 0°Sin 180° = 0 [ Since the value Sin 0° is 0]\xa0 |
