2) Determine the value of the following line integrals over the
indicated path. Note that the formulas change if the integral is
over a scalar function or a vector field.
a) fxy dx+xzdy + yz dz o(t) = ti+t²j+2k con t = [0, 1]. b) f(x² + y² + z²) ds o(t) = sin(t)i + cos(t)j +2k con t = [0, π/2]. c) x² dx + y² dy + z² dz o(t) = (4 sin(t), 4 cos(t), t²) con t = [
