How to input sin 2

WebAs many people have pointed out by now, sin 2 x is simply a "nickname" for ( sin x) 2. Therefore, sin 2 30 = ( sin 30) 2 = ( 1 / 2) 2 = 1 / 4. As it happens, though, there is another useful thing we can say about sin 2 x: sin 2 x = ( sin x) 2 = 1 2 ( 1 − cos ( 2 x)). We can see this using the double-angle formula for cosines: Web10 mrt. 2024 · Perform a simple SIN function with an easy to remember answer. For example, the sine of 30° is 0.5. On a scientific calculator, to find the sine of 30° for example, you type in 30, then press SIN to get 0.5. If you got a different answer, it probably means that your scientific calculator is not in degree mode.
