Paper 1 5 marks Difficulty 3

Interpret a sine graph with vertical shift

For \(y=1\sin(4x)+5\), state the amplitude, period in degrees, maximum value, and minimum value.

Worked practice: sine graph features

Read the amplitude and period, then use the vertical range to state the maximum and minimum.
