Trig Function Graphs

Trigonometric graphs (sine, cosine, tangent) are periodic wave functions. The sine and cosine graphs oscillate between −1 and +1 with a period of 360° (2π radians)

The calculator uses the standard published formula for trig graphs. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: y = A × sin(Bx + C) + D. Each step in the calculation is shown so you can verify the result manually.
