How do you graph #f(x)=Cos( x + pi/4 ) #?
1 Answer
See explanation.
Explanation:
#"Period" = (2pi)/b = (360^@)/b#
#(360^@)/1 = 360^@ "/cycle"#
#"Phase Shift" = -b/c#
#-pi/4 * 1/1 = - 45^@# phase shift
Make a list of points for every
A negative phase shift you'll move the plotted points to the left a positive phase shift adjusts the plotted points to the right.
