Hi Peter,

Glad you found it useful. If you are interested I have implemented an updated version which works properly now.

There is also a Cosine version too. You can find them here at our sister site:

I discovered your interactive graph when trying to find a program to show my student how the sine varies with the angle. I found the perfect one, even with more parameters A, k and phi. Thanks David.

Dilation factor?

It’s a Sine wave, what more can I tell you! Amplitude is reversed yes, just needs updating.

Why does your graph start going towards the negative direction of the y-axis?. When you reset it, the dilation factor is “positive one” from the x-axis, however when your graph resets, the “Amplitude” value is 1, but yet your graph turns out to be a negative sin graph (relection in the x-axis)

Thanks Donald, it is nice to know you found our interactive sine graph useful. This example is typical of the sort of application we create for our clients. Any feedback from yourself or some of your students would be welcome, as would any suggestions for future applications.

Also, we plan to release a much more comprehensive version of this particular example sometime in the future, so watch this space!

As an 8th grade Physical Science teacher I needed something to show my students about changing frequency and wavelength. Your interactive graphic fit the bill. Thanks
