How can I express shortly, that I use something for something?


I mean for example the following:

-Valuation of bonds by present value approach/method
-Valuation of bonds with the help of present value approach/method
-Valuation of bonds using present value approach/method

What would be right and the most common?


Those snippets, taken out of context, are not enough to clarify what you want to know, sorry.

it would be simply a name of a presentation

In that case I can’t help you as I don’t understand what you mean by ‘present value approach/method’.
Perhaps someone else will have more of an idea.
