Answer:
<h3>The solution of the given equation is x = 105 °∈ ( 0 , 2pi)</h3>
Step-by-step explanation:
Step(i):-
Given equation is sin x cos x = -1/4
![2(2sinxcosx) = -1](https://tex.z-dn.net/?f=2%282sinxcosx%29%20%3D%20-1)
we know that trigonometry formula
2 sin x cos x = sin 2x
2 ( sin 2 x) = -1
sin2x = -1/2
Step(ii):-
sin2x = ![\frac{-1}{2} = sin (\pi +\frac{\pi}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B2%7D%20%3D%20sin%20%28%5Cpi%20%2B%5Cfrac%7B%5Cpi%7D%7B6%7D)
<h2> sin2x = sin 210</h2><h2> 2x = 7π/6</h2><h2> 2x = 210°</h2><h3> x = 105 °</h3><h3>The solution of the given equation is x = 105 °∈ ( 0 , 2pi)</h3>
-2x^2+4x
