Title: Incorrect use of =>
Post by: dekoyl on November 08, 2008, 12:48:01 pm: Yesterday in exam 1, I decided to use $\implies$ to show mine different lines of working.
If I somehow used it in the wrong place, would I lose marks?
I'm not sure why I did $\implies$ . I don't usually do that..

For example, in the "show k = ____"
I did
$\int{}{}........ = 1$

$\implies ........ [ bla bla ] = 1$

$\implies ....... = 1$

$\implies ....... = 1$

$\therefore k = ............$ as required.

I did it in other places too.
