Question

Consider the blue vertical line shown above (click on graph for better view) connecting the graphs If y = g(x) = sin(2x) and y = f cos(3x). Referring to this blue line, match die statements below about rotating this line with the corresponding statements about the result obtained. The result of rotating the line about x-axis is The result of rotating the line about y-axis is The result of rotating the line about the line y = 1 is The result of rotating the line about the line x = -2 is The result of rotating the line about the line x = pi is The result of rotating the line about the line y = -2 is The result of rotating the line about the line y = pi The result of rotating the line about the line y = - pi a cylinder of radius x + 2 and height cos(3x) - sin(2x) an annulus with inner radius sin(2x) and outer radius cos(3x) an annulus with inner radius pi + sin(2x) and outer radius pi + cos(3x) an annulus with inner radius pi - cos (3x) and outer radius pi - sin(2x) a cylinder of radius pi - cos (3x) - sin(2x) a cylinder of radius x and height cos(3x) and outer radius 1 - sin(2x) is an annulus with inner radius 2 + sin(2x) and other radius 2 + cos(3x)
