I need help with these problems.
1.)Find the surface area by revolving r=1+cos theta about the x-axis.
2.) Write the equation of the hyperbola 9x^2-4y^2-36x+24y-36=0 in the standard form. Find its vertices, foci, asymptotes, and intercepts.
3.)Find the area of the region between the curves r=2 cos theta and r=2 sin theta.
