Question

The proper trigonometric substitution (some x = g(theta) determined by you) applied to the integral will convert it to one of the (simplified) form where A, D and C are integers. Enter the sum A + B + C of those integers. What is being computed on the interval [1, 5] in the expression The volume of the solid formed by revolving around the x-axis by discs. The volume of the solid formed by revolving around the y-axis using cylindrical shells. The arc length of The area of the surface formed by revolving around the x-axis What is being computed on the interval [0, pi] in the expression The volume of the solid formed by revolving y = sin x around the y-axis The arc length of y = sin x The area of the surface formed by revolving y = sin x around the x-axis None of the above.
