# Solve these equations graphically on the interval [0, 2π]. Sketch the graph and list the solutions. sin(2x) – 1 = tan x

We graph the two functions: y=sin(2x)-1 in black and tan(x) in red and note the intersections on the interval `[0,2pi]` :

The intersections (from a graphing utility) are approximately :

`x~~2.0687813` and `x~~5.210374`
