Trig: Pythagorean IdentitesCan someone tell me the pythagorean identites that are used for trig? Last edited by Saitenji (20050930 10:39:23) #2 20050930 17:13:08
Re: Trig: Pythagorean IdentitesThose two imply each other, and they also imply: Why did the vector cross the road? It wanted to be normal. #3 20051001 13:06:29
Re: Trig: Pythagorean IdentitesDoulbe angle identities are created by using the sum identiy's where both angles are the same. So instead of "sin(A+B)" you use "sin(B+B)" or 2b: Double the angle. You then replace B everywhere with A. A logarithm is just a misspelled algorithm. #4 20051004 10:46:55
Re: Trig: Pythagorean IdentitesYeah, I went over it more indepth today with my teacher 'cause I told her I didn't understand much. She was really nice about it and I believe that I am actually starting to remember several of these identities. Thanks for your guys' help as well though, wouldn't have been able to do my homework that night without it.
