The equation of the sinusoid will be y=Sin(2x)
What is an equation?
It is defined as the relation between two variables, for a sinusoidal wave the equation will be in the form of Sin or Cos.
if x=0 then sin(2*0)=sin(0)=0
if x= π/4 then sin(π/2)=1
if x= π/2 then sin(π)=0
Hence the equation of the sinusoid will be y=Sin(2x)
