Derivatives on HP 42S
Awhile back, a gem of a way to produce d/dx using the complex number capabilities of the HP 15LE was posted. It worked wonderfully, and could be used in solve to find extremums. I am stumbling over how to implement this on my HP 42S.
I attached the image of a sample program for the HP 15LE to take d/dx of (sin x)/x and the use of it in solve. How should I accomplish this on the HP 42S? |
