Explanation:
#"the standard form of the sine function is"#
#color(red)(bar(ul(|color(white)(2/2)color(black)(y=asin(bx+c)+d)color(white)(2/2)|)))#
#"where amplitude "=|a|," period "=(2pi)/b#
#"phase shift "=-c/b" and vertical shift "=d#
#"here "a=5/2,b=1,c=d=0#
#rArr"amplitude "=|5/2|=5/2," period "=(2pi)/7#
