If a 30 then sin2a

Web⇒ sin 2A = 2 sin A cos A Note: In the above formula we should note that the angle on the R.H.S. is half of the angle on L.H.S. Therefore, sin 60° = 2 sin 30° cos 30°. The above formula is also known as double angle formulae for sin 2A. Now, we will apply the formula of multiple angle of sin 2A in terms of A to solve the below problems. 1.

WebThen $\sin A$, $\sin B$, and $\sin C$ are actually the lengths of the sides opposite that three angles---that's essentially the law of sines. The area of any triangle is the product of the lengths of two sides times the sine of the angle between them, divided by $2$. So the area in this case is $(\sin A\sin B\sin C)/2$.
