Best ResponseYou've already chosen the best response.0What values for \(\Large\theta(0\le\theta\le2\pi)\) satisfy the equation? \(\Large2\sin\theta\cos\theta+\sqrt3\cos\theta=0\)

Best ResponseYou've already chosen the best response.1Factor \(\cos\theta\) out; \(\Large\cos\theta(2\sin\theta+\sqrt3)=0\) Then now we can split into two equations; \(\cos\theta = 0\) OR \(2\sin\theta+\sqrt3=0\) Right?

Best ResponseYou've already chosen the best response.0I guess so? I don't remember how I started working on this earlier, but I already have 2 answers, but there are 2 more

Best ResponseYou've already chosen the best response.0pi/2 and 3pi/2. I used the unit circle to find the values for when cos=0

Best ResponseYou've already chosen the best response.1ok. now we solve for \(2\sin\theta+\sqrt3 = 0\) Try isolate \(\sin\theta\).

Best ResponseYou've already chosen the best response.0ohhh \(\sin\theta=\sqrt3/2\) so the answers are \(\Large\frac{5\pi}{6}\) and \(\Large\frac{7\pi}{6}\)
