Explanation:
#"the standard form of the "color(blue)"cosine function"# is.
#color(red)(bar(ul(|color(white)(2/2)color(black)(y=acos(bx+c)+d)color(white)(2/2)|)))#
#"where amplitude "=|a|," period "=360^@/b#
#"phase shift "=-c/b ," vertical shift "=d#
#"here " a=1,b=1,c=-60^@,d=2#
#rArr"amplitude "=|1|=1," period "=360^@#
#"phase shift "=-(-60^@)=+60^@#
