Composite Trigonometric Function Calculator

Calculate properties of y = A sin(ωx + φ) and y = A cos(ωx + φ) including period, range, extrema, symmetry, and monotonic intervals.

Function Parameters
Configure your composite trigonometric function (A > 0, ω > 0)
A > 0
ω > 0
Any real
Current Function:
y = 1 sin(1x + 0)
Parameter Effects
Amplitude (A): Controls the vertical stretch. The function's range becomes [-A, A]. Larger A means taller waves.
Frequency (ω): Controls the horizontal compression. Period = 2π/ω (or 360°/ω). Larger ω means faster oscillation.
Phase (φ): Controls horizontal shift. Positive φ typically shifts left, negative φ shifts right (depending on the form).
Function Graph
Dynamically displays the graph of y = 1 sin(1x + 0), including key point markers
Sine Function
• Dots indicate key points (extrema and zeros)

Graph range: 0 to 4π. The graph updates in real-time as parameters change.

Calculation Methods
Period: For y = A sine(ωx + φ), T = 2π/ω (radians) or 360°/ω (degrees)
Extrema: Solve ωx + φ = key angles where sine reaches ±1
Symmetry: Use standard sine symmetry patterns, adjusted by transformations
Monotonicity: Analyze where derivative is positive/negative using chain rule

Frequently Asked Questions

This is the general form of a sinusoidal function where A is the amplitude (vertical stretch), ω affects the period (T = 2π/ω), and φ is the phase shift (horizontal translation).
