Explanation:
"the standard form of the "color(blue)"cosine function"the standard form of the 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^@
