flavoracle: nerdygeekyheaven: Okay but this actually does a good job of visualizing and conceptualizing where the hell cosine, sine, and tangent graphs come from. (Ignoring the fact that it’s a heart and not a circle, anyway)I wish I had seen this when I was actually taking trig and learning about those graphs WAIT Are you telling me there is a way there is a way to VISUALIZE what sin, cos, and tan ACTUALLY MEAN?! I mean look, it may have only been the very start of the 21st century the year I took calculus, BUT IT WAS STILL THE 21ST CENTURY. Why has no one explained this? Trigonometry is so friggin’ cool when it’s properly explained. It’s more about circles and cycles than triangles. It’s where you get to relate the five most important constants in math in a nice, simple, beautiful identity. -- source link
