RE: HP49-50G : tan(x) 50% faster than sin(x) or cos(x)
Cos evaluation
Indirect formulae A: « TIME 1 10000 START 3. TAN SQ 1 + INV DROP NEXT TIME SWAP HMS- HMS 3600 * "s" TAG » Time s: 3.207031 Direct from the calculator command: B: « TIME 1 10000 START 3. COS DROP NEXT TIME SWAP HMS- HMS 3600. * "s" TAG » Time s: .715088000002 —> more than 4 times faster It's clear from the above that "internal" calculation B reduces, logically, all the program manipulations shown in A. |
