Work out amplitude and period instantly with clear inputs, formula shown and shareable results.
For y = A·sin(Bx + C) + D the amplitude is |A|, the period is 2π/|B|, the graph is shifted horizontally by −C/B and vertically to the midline y = D. The range is D − |A| to D + |A|.
Amplitude and period
amplitude = |A|, period = 2π / |B|
Phase shift
shift = −C / B (right if positive)
Amplitude 3, period π ≈ 3.141593, phase shift −0.5 and midline y = 4.
No. Sine and cosine share the same amplitude and period rules; only the starting phase differs.
