<p>Guys, when using the solve function, how do you specify a domain for the values of x?</p>

<p>Like if you wanted to solve</p>

<p>sin2x = 3sin(x) where 0<=x<=2pi</p>

2

<p>you do: solve(sin2x=3sinx,x)lx>0 and x<2pi</p>

<p>but the < and > should be greater than /less than or equal to, not just greater than or less than. to get that, you dimond and the greater than sign for greater than or equal to.</p>

<p>the l means such that, and that will be on the first column in the middle of your 89(left side)</p>

<p>thank you!</p>
