I seem to have trouble now with integrating ln and e.

Haha, you are having trouble because you are learning sth you don't have to know at O'Level. You don't have to know how to Integrate Ln directly.

Having said this, **you note that you must know how to Differentiate Ln, e and Integrate e**

For more info on how to differentiate Ln and e, refer to this post >>

Okie how to Int e

Example

Int e^(2x+3) = e^(2x+3)/2 + c (since there are no limits given)

In short to Int e^(wadever) = e^(wadever) OVER (Differentiate wadever)
