using "and which"
Please help me to bring out the meaning and role ( function) of "and which, using integration" in the following sentence. "These produce results that would be more difficult and tedious to obtain by integration, and which, using integration, may be expressed in a form that is more difficult to interpret and understand"
Which is a pronoun. It refers to something previously mentioned (the results) and is used at the beginning of a clause that is going to provide additional information about that thing.
You may get a little confused because it is followed by [, using integration,]. This is a non-essential phrase and is surrounded by commas. the sentence can stand on its own without it.
, and which may be expressed....
