Transformations of the Sine Curve

This interactive animation shows the effect of adding a constant to the function.

This interactive animation shows how altering b in the function
y = sin(bx) changes the frequency/wavelength.

The Ambiguous Case of the Sine Rule

The powerpoint is digital and the activity is interactive. The two powerpoints are very well done - clear and profesional looking. The activity is nicely thought-out. Great job, Pam!

The Unit Circle and the Sine Curve

This animation from Lou Talman shows how the sine curve can be constructed from the definition of the sine function as the y-coordinate of a point on the unit circle.
