Question

Calculus question... Am I breaking a rule by doing this? equation soon to come

Answer 1

\[{dx \over dr}={dy \over dr}\]I want to cancel out the dr's to just get \[dx = dy\]

Answer 2

Then I can integrate. Can I do this?

Answer 3

that looks good to me
it would be equivalent to multiplying both sides by dr and integrating
\( \int \dfrac{dx}{dr} dr = \int \dfrac{dy}{dr} dr \)

Answer 4

the dr is canceled automatically

Answer 5

d/dr and integral with respect to dr are just inverse operations

Answer 6

Thank you
