Do I need to know long division while attempting my 4 year STEM degree? What use is it in anything besides math?

>> No.9348452

The only time I've ever used long division was in Calculus 2 in order to integrate improper fractions. Other than that, I haven't had to use it...yet.

polynomial long division has some random uses

Every single professor will assume you know it by heart, so If it comes in an exam you will be fucked. Though, is nothing you cannot learn in 2 days (not using the full days obviously).

This is a troll thread, right? What kind of retard can't do long division?

>> No.9349422

In my physics bachelor's, literally all the exams allowed calculators so we never needed it. That being said, I forgot my calculator for an exam once and it saved me from losing like a point probably (since getting the right expression is more important than the final computation)

Long division of polynomials will be useful computing limits and integrals. Also when you want to find the eigenvalues of a matrix you first want to try some rational roots and then do long division to reduce the polynomial.

When studying linear differential equations, same thing. You take the characteristic polynomial, try the rational roots, then reduce the polynomial by dividing it.

Basically, any course that studies polynomials or rational functions will need it.

numerical methods are useful in every stem degree, besides maths.

I'm sure you still carry around a book with logarithmic tables.
