Just need a little help starting out these problems
Solve each equation in the interval indicated:
1.) tanx-2cosxtanx=0 ; [0, 360)
2.) 2sinx+1=cscx ; [0, 360)
3.) sin2x=-sinx ; [0, 360)
4.) sin2x=-1/2 ; [0, 360)
i appreciate the help

factor out
then solve for
at and
solve for
if
then will go to 0
so and
so x = ,
