By signing up, you'll get thousands of step-by-step solutions to your homework questions. You can also ask And then, the first of these formulae becomes: Cos(t + t) = Cos t cos t – Sin t sin t. so that Cos 2t = Cos 2 t – Sin 2 t. And this is how we get second double-angle formula, which is so called because you are doubling the angle (as in 2A).

Latest answer posted November 07, 2015 at 10:01:03 AM `2sin(2x) + sqrt(3) = 0` Solve the multiple-angle equation. - Ta có phương trình \(cos2x-3sinx-2=0\Leftrightarrow 2sin^2+3sinx+1=0\) \(\Leftrightarrow \bigg \lbrack\begin{matrix} sinx=-1\\ sinx=-\frac{1}{2} \end{matrix Click here👆to get an answer to your question ️ Let 2sin^2x + 3 sin x - 2 >0 and x^2 - x - 2<0 ( x is measured in radians).

so you'll get 1 - 2sin²x - 3sinx - 2 = 0. you can let sin x = y. so you'll have 1 - 2y² - 3y - 2 = 0. rearranging them will give you 2y² + 3y + 1 = 0. solving this will give you 2 values of y which is -1/2 and -1.
