I’m rather happy to report I’m holding onto 483 points out of a total 500 possible points (which means my grade is 96.6%). I just need to survive the 200 point final.
Also note – the triangle app for the TI you see below requires the latest OS for the TI-89 or you’ll get errors. The latest OS is WORTH installing. Its got some really nifty trig tricks available to it.
