Finding areas between graphs

  1. Jan 26, 2010 #1
    find the exact area between y=ex, y=2, and the y axis

    im not looking for a solution, just hints on how to get started.
    would i just go ahead and integrate the function from 0 to 2 or would i solve the function for x and then integrate or are those 2 idea just completely wrong?

    thanks
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Step 1 is to sketch the region whose area you want to find. Then find where y = ex intersects y = 2. After you have done that, you need to find the typical area element (either horizontal or vertical) and the limits of integration (which are NOT 0 and 2). There is a bit more to this problem than simply "integrat[ing] the function from 0 to 2."

    mark is right. you are looking for an area near 1.
