Sketch the region enclosed by y=e^2x, y=e^6x, and x=1. Decide whether to integrate with respect to x or y. Then find the area of the region.

  • Calculus 2 - ,

    since e^6x is greater than e^2x on [0,1], I'd integrate with respect to x.

    Int(e^6x - e^2x dx)[0,1]
    = 1/6 e^6x - 1/2 e^2x [0,1]
    = (1/6 e^6 - 1/2 e^2) - (1/6 - 1/2)
    = 1/6 e^2 (e^4 - 3) + 1/3
    = 63.8
