The equation for sinusoidal functions is where
"a" is the vertical stretch / compression
"k" is horizontal stretch / compression
"c" is vertical shift
"d/K" is horizontal shift...
so if a graph is given to me and i need 2 find it's equation... how do i know the horizontal stretch
i scanned this sheet given by my teacher... if u guyz could do one of the questions for me and explain me how to do it...
srry about the pencil marks... please ignore them..
