Because most calculators won't let you put in the original equation and actually get a number out. (Of course, most calculators also don't offer the Lambert W function as an operation, but there are some more advanced ones that do...) This sort of thing is also useful if you are not trying to actually find the _numerical_ result, but just want to find a symbolic value of k that you can plug into some other equation, etc.
Nice one, thanks!
the fish thing is actually good to remember
Saw the same thing with apple
Why does this say both "JAPAN" and "Harvard Exams"? Last I checked, Harvard is nowhere near Japan.
What's the point of doing all this if in the end you still have to use a calculator to get the answer🤦
