for the function y=sin x, the statement that is not true is
a) the amplitude can be found by determining the distance from a maximum point to the x-axis.
b) the amplitude can be found by dividing the vertical distance between (pi/2 , 1) and (3pi/ 2, -1) by 2
c) the period can be found by finding the horizontal distance between (0,0) and (2pi,0)
d) the period can be found by determining the horizontal distance between any two consecutive x-intercepts
