You never specified what type a function is, such as 𝑓 : ℝ → ℝ?
Fair enough, I changed “never” to “rarely” :) I’m actually curious, did you have to specify the ‘type’ often?
If 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.
Also, everyone keeps using one-letter variable names without any comments in code
Terrible naming all around in maths, half the shit is named after dead French or German dudes.
Leonard Euler was just the 16th century maths version of Alan Smithee that people wrote on papers as a joke, and you can’t convince me otherwise.
My experience with math class has been quite different. Most exercises specify the domain of the equations, and I’ve been taught to always work out the set of possible solutions (when it’s non-obvious) before solving an equation, though I usually forget to do this and still end up with impossible states…
And then use an operation which is only defined 2 pages later…
also in calculus the answer is typically 1 or 0
