Derivative of sin(x)

Desmos applet to introduce derivative of sin(x).
Also includes an opportunity to compare subsequent derivatives, as per Marc Renault’s resources (here).
Inspiration:

Continually amazed at the power of this simple animation. Showed to students for 3 minutes, after which they hypothesized that the derivative of sine:

• is continuous
• is periodic
• is bounded by 1 and -1
• is even
• takes zeroes at π/2 + kπ#math #mathchat #APCalc pic.twitter.com/wWGZn6Td70

This is my second attempt at creating a ‘prezi’ presentation. It is currently ‘in progress’ and I am still not certain of the best way to ‘store it’ for future access, so have placed a link here for the time being.

With this particular prezi, I haven’t yet decided if I want it to include trigonometry, or if I want this to be separate.
