Calculus How do you choose problem sets in Courant's calculus texts?

  1. Dec 13, 2017 #1
    I'm going to use Courant's volume 1 and 2. I don't want to try every problem in the book, so how do I go about choosing problems to know if I understand the material?

    Some techniques that I use :

    A) : Just look at the problems, if they seem hard do it else ditch it.

    Eg: 1) ##\displaystyle \int_0^\infty \dfrac1{x^2} dx## and 2) ##\displaystyle \int_0^\infty \dfrac{\sin x}{x} dx##. You shouldn't even touch problem 1 but you should definitely try to solve problem 2.

    B) : For problems like :
    Solve the following differentials equations
    1) ##y' = x##
    2) ##y'' + y' = x##
    3) ##y'' + y' + y = x##.

    Here do only problem 3 and leave rest of it.

    C) : Don't be stuck on a single problem for more than 30 mins. Leave the problem if you can't do it and come back after few days to it.
