(a) Using the axes below, sketch the graph of \(y = \sin x\) for values of \(x\) from 0° to 360°. You must label any important values on both axes. [2]
(b) Circle the value that is equal to sin 200°. [1]
sin 20° sin 100° sin 160° sin 220° sin 340°

Comments
Correct sine curve with 1 and −1 shown on the y-axis and 180° and 360° shown on the x-axis.
B2
Multiple cycles gain both marks only if both axes fully correctly labelled for x between 0 and 360.
If B2 not awarded, B1 for a sine curve (single cycle) with missing values on axes OR B1 for multiple cycles with (only) x axis correctly labelled.
