The app is larger than those in our previous lessons, so we divide it into several parts.
In this lesson, we are going complete the core element of our clock, drawing the seconds hand. We will learn the draw line & set line width function in Canvas.
We will also explain how we can use cosine(Cos) and sine(Sin) function to help us finding the x y coordinates of the seconds hand.
I don't want to make the video too long, so I only demonstrate how to draw the seconds hand in this lesson.
I will put the answer of minutes and hours hands and explain it in next week's video.
