questionable proofing method (1 Viewer)

[underthesun]

For proofing, instead of going through long workouts to go:

a = (the long working) = (some more working) = b

can you just go put a = b, then try to prove both side's equality? that is LHS = RHS..

and can you do that for induction.

Yeh, do the initial working on scrap paper, and write the final working backwards.

i see. Hmm, i hope i'll be able to do it fast enough.
