Consider this graph, of sin(x)

You can see that where sin(x) = -1, x = 3/2 Pi (270 degrees). So that is the first of many solutions, which recur every 2 Pi (or 360 degrees) plus or minus from the first solution.

tan(x/2)=sin(x)/(1+cos(x))
Setting x/2=45, means that x=90 (degrees)
But cos(90)=0 and sin(90)=1. Thus tan(45)=1/(1+0)=1.
