tan^2x = 2tanx*sinx
(tan^2x)/tanx = (2tanx*sinx)/tanx
tanx = 2sinx
sinx/cosx = 2sinx

x = [tex]pi[/tex]/3
[tex]\alpha[/tex] = [tex]pi[/tex]/3 and 5[tex]pi[/tex]/3
Not sure what I'm doing wrong.
The answer is [tex]pi[/tex]/3 and 5[tex]pi[/tex]/3 and 0, and [tex]pi[/tex]
Thanks for the assistance, I greatly appreciate it.
