Hi folks,

in the attachment you can see two circles intersecting each other. My task is to find the area bounded by the two circles and points A and B.

Clearly this area will be the area, A under the top curve (red) - area under the bottom curve (blue)

so, $A = \int_{0.294}^{0.956} y_{1} dx - y_{2} dx$ and $y_{1} = \sqrt{4x - x^2}$

my problem is how to deal with the second equation: $x^2 + y^2 -4y + 3 = 0$ how do I get y in terms of x so that I can integrate y dx?
