TopicTrig Graphs & Exact Values
TypeSketch or identify transformed graph
DifficultyEasy -1.3 This is a straightforward recognition question requiring only knowledge that sin(x + 90°) = cos(x), which shifts the sine graph left by 90°. Students simply need to identify which graph starts at y=1 when x=0°. This is basic recall with minimal problem-solving, making it easier than average.

2 One of the diagrams below shows the graph of \(y = \sin \left( x + 90 ^ { \circ } \right)\) for \(0 ^ { \circ } \leq x \leq 360 ^ { \circ }\) Identify the correct graph.
