Cos evaluation

Indirect formulae A:
« TIME 1 10000
START 3. TAN SQ 1 + ƒ 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.
