What you can explore
- Control amplitude A, horizontal stretch b, phase φ (in radians or degrees), and vertical shift D in one form.
- See derived quantities—amplitude, period, frequency, phase shift, and range—update instantly beside the main equation.
- Synchronise the unit circle and function graph so θ, cosθ, sinθ, and y(θ) are always aligned.

استاد کے نوٹس
- Connect amplitude and vertical shift directly to the peaks and midline before inviting students to move θ.
- Pause animation at special angles to highlight cosθ and sinθ coordinates, then restart to show continuity.
- Use the CSV export to plot the same curve in spreadsheets or graphing utilities for comparison exercises.
Frequently asked questions
How کیا مجھے represent a constant function when b = 0?
Set b to 0 and choose any φ. The explorer evaluates y = A*f(φ)+D, so the graph collapses to a horizontal line and derived نتائج show an infinite period and zero frequency.
کیا میں type expressions like π/4 or √3/2?
Yes. The fields understand common math expressions including pi, sqrt(), parentheses, and basic arithmetic, so π/4 or sqrt(3)/2 are parsed safely without using eval.
