-- Right triangle: "The ratio between my height and my hypotenuse is the sine of my angle!" Small blob: "The sine of your angle? Is that important?" Right triangle: "I am told it is! I am very special because my ratio is the sine of my lower angle!" Small blob, to sine of angle: "What makes you so special, abstract relation with a label?" Sine of Angle: "I describe how rotation and vertical translation go together! You'll need me if you ever want to simulate a bicycle to calculate the ideal height of its seat!" Small blob, to right triangle: "Why would I ever want to simulate a bicycle?" Right Triangle: "Sorry, is this about vertical things, horizontal things, diagonal things, or angular things?" Small blob: "Umm ... I think is vertical and angular." Right Triangle: "Perhaps the arcsine is your answer. Bicycles sound kind of old, and so it the arcsine. If you ever want to know an angle based on a height, the arcsine is your friend!" Small blob: "But why would I ever want to know that?" Arcsine: "Your angle is indeterminate. Are you sure you're a real number?" Small blob sat a little. Different small blob: "Trigonometry sure is silly, isn't it, small blob?" Small blob: "Why are things trigonometric instead of something that makes sense?" Different small blob: "I think Karl tries to do trigonometry to relax sometimes." Small blob: "Ohhh! Maybe I can help him!" Small blob to right triangle: "One moment, friend trigonometry." Small blob to different small blob: "Are you sure he's not trying to tell a story? Isn't this a post to the internet?" Different small blob: "Ummmmmmmmmmm. Let's tell an old mind control story."
