Integrate between two functions

Hi,

So firstly sorry I’m not at home so don’t have an example to show but what I’m after is integrating an area and performing multiple tasks between two limiting functions.

I.e I have a function which I’m going to integrate underneath. this function is in terms of x. (A line that increases up the y axis as x increases)

Then I want to introduce two functions in terms of y ie vertical lines.

I then want to integrate the area under the first line and between the second two. Any idea how I do this? FYI I use prime 3

Cheers

Hi Luc,

Thanks for that. Yes, in a way I think that gets me to where I want to be.

Now I am back at work, see attached image of the sort of thing I am looking at. What I am after is integrating the area under my blue line and to the left of both the red and black lines. I have experimente with a few ways of doing this and as you say can do this by taking areas away from eachother. Obviously for now I am working with simple shapes but this could get quite messy when I apply the logic to my final objective which is much more complex.

Cheers,

A
