    Please look at the two attachments,

    in both the cases why different formulas are used to find ao ???

    the book mentioned the following formula ao = 1/∏ ∫ f(x)dx (limits are 0 to pi )

    then why in these question the teacher use different formulas :confused::confused::confused:



    please explain the reason
