minus-squarexigoilink23•edit-21 year agoYou never specified what type a function is, such as 𝑓 : ℝ → ℝ?
minus-square@snek_boi@lemmy.mlOPlinkfedilink8•1 year agoFair enough, I changed “never” to “rarely” :) I’m actually curious, did you have to specify the ‘type’ often?
minus-squarexigoilink6•1 year agoIf I remember correctly, good textbooks always specified the type. There were even exercises like “find the maximum possible domain of this function”. And in higher-level mathematics, it’s pretty much a sin to not specify the type.
