Trigonometric Graphs

The interactive applet below demonstrates the changes in Amplitude, Period and Axis of Curve as the constants A, B and C changes in the equations:

  • y = A sin Bx + C, and

  • y = A cos Bx + C.

What did you observe as the A changes?

The amplitude of the sinusoidal function increases with the magnitude of A.

Tangent & Cotangent Graphs

The interactive applet below demonstrates the changes in Period and Axis of Curve as the constants A, B and C changes in the equations:

  • y = A tan Bx + C, and

  • y = A tan Bx + C.
