Simplify double angle formula

Webb23 okt. 2016 · This can be simplified as (sin6x)/2 According to the double angle formula: sin2x=2sinxcosx From this we can say that: sinxcosx=(sin2x)/2 or more generally: sinnxcosnx=(sin2nx)/2. If we apply this rule to the given example we get: sin3xos3x=(sin6x)/2 WebbWe can use Euler’s Formula to draw the rotation we need: Start with 1.0, which is at 0 degrees. Multiply by e i a, which rotates by a. Multiply by e i b, which rotates by b. Final position = 1.0 ⋅ e i a ⋅ e i b = e i ( a + b), or 1.0 at …
