Question

how can you decide when it is necessary to use substitution to find an indefinite integral?

Answer 1

practice

Answer 2

substitution cleans up the argument, so "needing" it is not all that of a requirement really

Answer 3

I am reading a section in the text book. In the practice section it says " determine when it is NECESSARY to use substitution" so I just wasn't sure

Answer 4

lol, id say when you got an ugly integrand, give it a shot :)

Answer 5

Is there some rule that says when the degree of the numerator, of a rational function, is greater then the denomintor you must do long division first then integrate the result?

this might help some

Answer 7

there are no "rules" to integration in that respect. There are common sense things, give it a shot things, try your luck things; but integration is more of an art than a science

Answer 8

ok I am going to check it out. I am at a high b in calc one right now. I have a test monday on integration then a final on tuesday. I will watch those links. thanks for your help

Answer 9

most integrands youll never be able to solve with what your learning to do now; these are just to give you the confidence that integration works ....

Answer 10

good luck :)
