# C3/C4 Area under curve/Integration help

Announcements Posted on
Why bother with a post grad course - waste of time? 17-10-2016
1. Hi guys
Im doing q8 iv in the paper below. I generally get these questions wrong. The style is 'find the area under the curve f(x) between 2 points'. Then the following question says find the area under the curve g(x) which is a translation of the curve f(x). Is there some general rule for finding the area??

in this example i cant see why i should 1 x pi/4 to the answer

thanks for any help

is a translation of to the right and up.

So the area under between and is clearly the same as the area under between 0 and , if is just shifted to the right.

But is also shifted up and so this creates a rectangle with dimensions
and underneath it, so you add this on.
