Alevel maths question Watch
A) express sinx-root3x in form Rsin(x-a), with R>0 and 0<a<90
B)Hence sketch the graph of y=sinx-rootcosx for -360£<x£<360
From part A) I get the equation y=2sin(x-60) and I can sketch it but I don’t get why the domain still remains -360 and 360 when y=sinx is translated by 60 to the right, in the mark scheme. Wouldn’t it be -300£<x£<420 ???
