When do we use the Trigonometry method- Soh cah Toa in everyday life?
In every day life, I’m not so sure, and everyone’s “everyday life” surely varies. But, as a programmer, graphics is full of trigonometry. (So, I imagine, those cool Matrix-y “bullet time” camera arcs are also full of trigonometry. http://en.wikipedia.org/wiki/Bullet_time The other day, I was using http://www.processing.org/ and wanted to have the camera move in a circle around my “scene”… So, I had “theta” be the time variable, and computed the camera’s x and y coordinates as radius * sin(time), radius * cos(time). That kind of thing I use all the time. If I wanted to rotate an object in two dimensions, I’d use the rotation matrix, which is also all about trigonometry. All the stuff people take for granted in Photoshop is likely full of trigonometry. Triangulating where you are from GPS requires trigonometry (among other things). As does finding out which cell
