use the best method to solve the following exercise and explain.

3. The cross-sectional area shown is the shaded area between the function y 2/1-x2 (half an ellipse) and y cos( The area A of the cross section can be calculated by: dx 1 dA The coordinate of the centroid of the area can be calculated by: ye M. where M is the moment of the area about the x axis, given by: Use all methods that apply for the problem. You can use computer software as Matlab user-defined functions or MathCad explicit solution. Compare results and rank methods from best to worse
