1. Use the integration capabilities of a graphing utility to approximate the surface area of the solid of revolution. (Round your answer to four decimal places.) Function: y = sin(x) Interval: [0, pi/4] revolved about the x-axis 2. Use the area of a surface of revolution equation 3. This was plug into the formula sin(x) sqrt(1+cos(x)^2) than i integrated it , and it became a mess. can anybody help me solve this, or even with a ti calculator if possible?
