can you answer b of the photo 2. Find the principal value of (a) (-i (b)...
help pleasee ignore the first photo, i need help with number 2 4. Let F(x, y, z) = (e" cos(y) + yz, xz - e" sin(y),ry+z). Compute 5.F-ds , where c: [0, 1] → R is given by c(t) = (tet, arcsin(t),t +1) 4. Let F(x, y, z) = (e" cos(y) + yz, xz - e" sin(y),ry+z). Compute 5.F-ds , where c: [0, 1] → R is given by c(t) = (tet, arcsin(t),t +1)
I get C but the answer is B, can you please explain why B is the correct answer instead of C (4) The appropriate trial solution to the 5-th order differential equation )+sin(r) is (A) A Bsin(x)+Ccos(s) (B) AzBrsin(r) Ca cos(a) sin() + Ccos( (D) ArBr3C Dsin(x) (E) none of the above.
