Q1) Determine the gradient of the following scalar field V = e(2x+3y)cos5z Q2) Given f = x²y + 3z + 4, find (i) Vf. (ii) V²f, and (iii) a unit normal to f = 0 at (1, -2, 4). Q3) Find the divergence and curl of the following vectors: A = ey a, + sinxy a, + cos? xz a, Q4) Given the vector field R = (2xły + yz)a, + (xy² – xz')a, + (cxyz – 2x²y²)a, Determine the value of c for R to be solenoidal. (Note: solenoidal means the divergence equal to zero) Q5) If the vector field T= (axy + Bz³)a, + (3x² – yz)a, + (3xz² - y)a, is irrotational, determine a, B, and y. Find V-T at (2, -1, 0). (Note: irrotational means the curl equal to zero)
