hi, I am reading Prime Obsession and john talks about Big o. He goes if Function A is trapped within + and - of function B then F(A) is Big O of F(B) So, y=Sin x is Big O of Y = 1 right? He also goes that if F(A) is Big O of F(B) then so is any multiple of F(A). so y=2sinx is also big O of Y=1? Even though is breaks the limit infinite amount of times? Any clarification appreciated. Thanks!
