Explanation:
The standard form of the
color(blue)"sine function"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=1/2,b=2,c=0,d=0
rArr"amplitude "=|1/2|=1/2," period " =(2pi)/2=pi
