Does one say

Plugging in that value into the previous equation...


Plugging that value in the previous equation...

or something else?

pluggin in into is for sure wrong - if you remove the in in the first sentence I think you will be fine – mplungjan Apr 11 '11 at 6:19
What happened to good old "substitute"? – Emre Apr 11 '11 at 6:46
Well... I have used "substitute" many times in my text. Therefore I have sometimes decided to plug in "plug in" instead of "substitute" ;-) – Marco Apr 11 '11 at 8:19

A combination of your two examples would be correct:

Plugging that value into the previous equation..

In this sentence you are dealing with the phrasal verb 'plug in', which has then been split by the noun ('that value').

@mplungjan: Thank you for your comment as well. I upgraded it! – Marco Apr 12 '11 at 19:20

Either "Plug in that value" or "plug that value into" are fine depending on the rest of the sentence, but not "Plug in that value into".

Removing the in could fix the sentence. – Noah Jun 8 '12 at 23:48
@Noah That's what I said. – Kevin Jun 11 '12 at 19:38
