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?
