why does wolfram alpha interpret "d/di" as me wanting to differentiate with respect to the imaginary unit? that doesn't even make any sense
@Erin that, and also it just seems like wolframalpha should be able to deduce that I am not asking it to differentiate with respect to a constant
I mean, you wouldn't enter ∂/∂2 would you?
@Felthry exactly, everyone knows the imaginary unit is j!
