    equations are sin(x) and cos (x) respectively. They are the fundemental characteristic graphs of sin and cos

    so the equation for this would be y=sin(x). as you can see in the quadrent thing i have posted above, sin(0)=0, sin PI/2=1 , sin PI= 0, sin 3Pi/2=-1, sin 2Pi=0 so according to this they have drawn the graph.
