Webb3 nov. 2024 · 2 Answers Sorted by: 6 Generally sin 2 x is used as shorthand for ( sin x) 2 = ( sin x) ⋅ ( sin x), which is different from sin x 2. You can make it less ambiguous by writing the latter as sin ( x 2). Edit: You just have to be careful when you see sin − 1 x, which … Webb\sin^2 x is not the same as 2\sin x \cos x. I think you confuse this with the identity \sin(2x)=2 \sin x \cos x. On the other hand, we have the identity \sin^2 x = \frac{1}{2}(1 - …
