**Solve sin(2x) - sin(x) = 0? Yahoo Answers**

19/11/2011 · Best Answer: sin x = 0 => x = k?, where k is an arbitrary integer. sin 2x = 0 => 2x = k? => x = k?/2, where k is an arbitrary integer. But the solutions x = k?/2 include those for x = k? -- whenever k is even. So the single formula for the solution is x = k?/2.... 19/11/2011 · Best Answer: sin x = 0 => x = k?, where k is an arbitrary integer. sin 2x = 0 => 2x = k? => x = k?/2, where k is an arbitrary integer.

**How to solve sin2x=1/2 Quora**

Doing a C4 Q and have kind of forgotton C2 :/ With sin2x = 0 , I thought you'd take sin inverse both sides to get 2x = 0 but then that doesn't make sens how to use solver in excel 2017 Doubling the sin x will not give you the value of sin 2x. Nor will taking half of sin x, give you sin (x/2). Nor will taking half of sin x, give you sin (x/2). We can develop the double angle formulas directly by using the addition formulas for sine, cosine and tangent.

## How To Solve Sinx Sin2x

Of course, there are other ways, this is only a simple and relatively naive approach. You could split the interval $[0,\pi]$ in more than two intervals (using other expansions of the solution), and you could find optimal polynomial approximation, or rational approximation (the latter is probably what would be used in a more robust implementation).
