Instructor: “So this expression approaches 0.”
Student: “What do you mean it approaches? Why isn’t it just 0?”
Instructor: “Well, if the numerator is divided by larger denominators, it gets smaller and smaller. Eventually it’ll approach 0.”
Student: “So it’s zero.”
Instructor: “No, it approaches zero.”
Student: “Argh!”
And you can’t forget indeterminate forms of limits.
Instructor: “Since this limit is infinity over infinity, we use L’Hospital’s rule.”
Student: “Doesn’t infinity divided by infinity cancel out to one?”
Instructor: “No, you cannot divide infinity by infinity.”
Student: “Argh!”
kasuo…aaaaaaaaaaaaaaaarrrrrrrrrrrrgh!! Reading that just gave me a headache.
I am truly dyscalculic…anything beyond 1+1 is pretty much incomprehensible to me in any written form. Aren’t numbers abstract constructs anyway? My checkbook says they are…hmmm.
Arithematic be abstract concept, according to Gottlieb Frege; like the beard of the present king of france. Nobody pays much attention to his ideas these days anyway.
What’s that theory called that ‘you will never be able to get where you’re going due to the fact that getting there involves getting halfway there, and as there are an infinite number of halves it is impossible to reach your destination’.
