Please I need help for #6 and 7

6. Express the ellipse in a normal form x2 + 4x + 4+ 4y2 = 4. 7. Compute the area of the curve given in polar coordinates r(0) = sin(0), for 0 between 0 and T For questions 8, 9, 10: Note that x2 + y2 = 12 is the equation of a circle of radius 1. Solving for y we have y = v1 - x2, when y is positive. 8. Compute the length of the curve y = V1 -12 between x = 0 and r = 1 (part of a
