I seriously do not understand anything about this problem Please help.

The equation of an ellipse centered at the origin is

(x^2/a^2) + (y^2/b^2)=1

The area of the upper half of the ellipse can be determined by finding the area between the ellipse and the x-axis (y=O). The total area of the ellipse is twice the area of the upper half.

(a) Solve the equation of the ellipse for y.(You will obtain two solutions,since there are two y values on the ellipse at every x value). Verify that the positive y values are returned by

y=b/a*square root -(x^2)+a^2

Please help me.
