Let’s begin with a task that needs to be completed in a visualization. Visualizations are controlled by scrolling and using items depicted in orange. Students need to find a correct solution in order to proceed. It is also possible to use a hint or to give up.

Let us examine the graph of the sine function and observe how it is related to the unit circle. Try to configure the visualization so that $\sin\alpha = 0{.}5$ holds and then press Answer.
