Trig...should I start by squaring both side?
Fing the solutions that are in the interval [itex][0,2\pi)[/itex]
[tex]\tan 4t-\tan 7t=1+\tan 7t\tan 4t[/tex]
Use an addition or subtraction formula.
[tex]\tan(a+b)=\frac{\tan a+\tan b}{1-\tan a\tan b}[/tex]
Should I start by squaring both sides, or move everything to one side and set equal to 0?
I tried both ways and I'm stuck after that step either way.
