Let S be the parametric surface, parameterized by r(u, v) = e" cos vi + e“ sin vj + uk, (u, v) E D = [0, 1] × [0, 1]. (a) Let æ be the value of | x at (u, v) = (0, 7/2). What is the value of (b) What...

Need help with this question. Thank you :)

Extracted text: Let S be the parametric surface, parameterized by r(u, v) = e" cos vi + e“ sin vj + uk, (u, v) E D = [0, 1] × [0, 1]. (a) Let æ be the value of | x at (u, v) = (0, 7/2). What is the value of (b) What is the total charge on the surface S if the surface charge density is given by restricting the function o(x, y, z) = /1+x² + y² to S ? (1) v27(e – 1) (2) (3e + e3 – 4) 22 of 24 (3) ((1+e²){ – 2#) (4) none of the other answers. Your answer to (a). . Your answer to (b).
