Figure 3 shows part of the curve \(C _ { 1 }\) with equation \(y = 3 \sin x\), where \(x\) is measured in degrees.
The point \(P\) and the point \(Q\) lie on \(C _ { 1 }\) and are shown in Figure 3.
- State
- the coordinates of \(P\),
- the coordinates of \(Q\).
A different curve \(C _ { 2 }\) has equation \(y = 3 \sin x + k\), where \(k\) is a constant.
The curve \(C _ { 2 }\) has a maximum \(y\) value of 10
The point \(R\) is the minimum point on \(C _ { 2 }\) with the smallest positive \(x\) coordinate.
- State the coordinates of \(R\).
