I hope this LaTeX works. It’s the first time I’ve tried using it in a WordPress environment 🙂

]]>Thanks for this great answer. We wanted to cite this generalized Ito’s lemma in our paper and were wondering what is a good reference to cite.

ABSTRACT

All of the above are undefined on the z-axis (sin = 0), where there is a coordinate singularity. However, by taking the limit as , we may obtain well-defined values for some or all of the above expressions

1 INTRODUCTION

A vector field has the equation, in cylindrical polar coordinates (, , z),

Find the divergence of F and the value of n for which the divergence vanishes for all .In cylindrical polar coordinates,

and clearly .

is therefore a source-free field everywhere except on the z axis.

]]>Could you please give me a reference on this stuff?

I need a reference book having results like Lemma 9. Any help will be greatly appreciated.
