Hi guys, I have the following question, thank you

2) Describe the main steps for evaluating the line and surface integrals: a) [21} - d? , L b) [I 21 - dS, S Where A is a vector function which is continuous on L and S and 15 is the unit normal vector of surface S. Here, L is the curve given by Ht) = 9603)? + y(t)j + z(t)lE, 131 S t S t2, and S is a nite portion of a simple surface defined by (i) Z = K9637) (ii) x = x(u, v), y = y(u,v), z = z(u,v) respectively
