SOLUTION: Determine the phase shift for y=1/2cos(5piex-3)

Question 882509: Determine the phase shift for y=1/2cos(5piex-3)
Answer by Edwin McCravy(20081) (Show Source): You can put this solution on YOUR website!

y = a�sin[b(x+c)] + d  or y = a�cos[b(x+c)] + d   

amplitude = |a|
period = 

Factor out 



compare to

y = a�cos[b(x+c)] + d  



amplitude = |a| = 
period =  = 
phase shift = |c| =  right since negative
vertical shift = |d| = 0 so no vertical shift
