Homework Help: Area under a polar curve

  1. Oct 4, 2012 #1
    1. For what value of α is the area enclosed by r=∅, ∅=0, and ∅=α equal to 1?

    2. x=rcos(∅)

    3. x=∅cos(0)

    Don't know what to do after this

    There is no point nor any need for rectangular coordinates for this problem. What is the polar coordinate integral formula for area inside r = f(θ)?
