Hello

Continuing with this problem, shown in the picture, where the parameterization for S was determined, how do i now calculate the area/surface of S. Could you help set up the integral for this equation?

(x, y, z) = (cos z, sin z, z), − < z <
Explanation:
Step 1:
y = x tan(z)
with:
x>0, x²+ y² = 1
−√ < ± < √
Step 2:
sin(z)
y = x cos(2)
Step 3:
substitute y:
x²+x2. sin².
cos2
Then we get:
=
2 . (cos's+sin= 2)
Hence we would get:
x² = cos² z
Step 4:
Since
x0, cos z> 0
We would get:
x = COS z
1
sin(z)
y = cos z.
== sin z
cos(2)
Hence the parametric form is:
(x, y, z) = (cos z, sin z, z), — √ <≤ z <
