  • Tips For How To Understand Application of Integrals In Physics
    Volume integrals are where the real trouble starts If you know you have to take the integral of something in 3-dimensional space, you could start having problems A lot of problems typically do have you integrate towards infinity which in cartesian is coordinates is pretty easy
  • Creating Big Integrals in LaTeX: Tips and Tricks - Physics Forums
    I search google and different math sites but came with not answer for making an integral big How do I do it please? ##\\int## is too small sometimes
  • Swapping Integrals and Sums: When is it Justifiable? - Physics Forums
    No, the sums in joshmccraney's post are infinite sums, so you cannot guarantee that exchanging the integrals and sums is valid Usually the infinite sum needs to be uniformly convergent to swap the sum and integral
  • Are there mathematicians that dislike integral calculus? - Physics Forums
    Solving integrals by hand is difficult and prone to errors, and the techniques such as integration by parts, partial fraction decomposition, and trig substitutions only work for a small subset of integrals and I do not see the point of avoiding technology like Wolfram Mathematica for mathematical research
  • Fourth Integral: What is the Answer? - Physics Forums
    Double and triple integrals do not necessarily represent areas and volumes, you can compute both area and volume (in some special cases) with a single integral! In your analogy though, an n-dimensional integral generally represents and n-dimensional volume, of which 2 is area and 3 our 'classic' volume
  • What is the real-world application of triple integrals? - Physics Forums
    Homework Statement I know that a single integral can be used to find the area under a y = f(x) curve, but above the x axis Correct me if this example of a double integral is invalid: If I hold a piece of paper in mid air and it droops, the double integral will give me the volume of the object
  • Why Split Improper Integrals? - Physics Forums
    It just seems tedious, where, if you get an integral which is not only bounded by infinities, but also have discontinuities , you would have to split it into at least 4-6 integrals Take my friend ineedhelpnow's integral
