I need a little help with a school project of mine. Its for my pre-calculus class. We all had to pick a real world situation and somehow relate trig. and advanced mathematics to our subject. We have to write a 5 page paper on it and present it to the class also. Of course me being a plane freak, I had to choose aviation as my topic. What Im asking of you is to give me a few applications to aviation that I can use. Im not talkin simple stuff like 360 degrees on a navigational radial, I need a bit more complicated stuff like maybe polar coordinates having to do with GPS. Or anything having to do with aerospace engineering would be good also. Just anything really relating math to aviation. Any help or suggestions would be greatly appreciated. Thank you very much!
