So i understand trig graphs until it involves FOR INORMATION - where i have put < i mean equal to or less the ni just dont know how to math it on here. thanks in advance
sketch the graph of
solve the equation for
give your answers in the form

for the first one pi= 180 degrees, therefore it is asking for a normal sine graph between 0 and 360 degrees however it wants the axis marked in radians e.g. pi=180 degrees,
2pi=360 degrees and so on.
for the second one 2sinx=-1
therefore sinx= -0.5
therefore x= 210, 330 degrees and remembering that pi=180
x= 7/6 pi or 11/6 pi
does this help??
