(7.5 points) Let C be the oriented closed space curve traced out by the parametrization r(t) = (cost, sint, sin 2t), 0<t<27 and let v be the vector field in space defined by v(x, y, z) = (et - yº, ey + r), e) (a) Show that C lies on the cylinder x2 + y2 = 1 and the surface z = 2cy. (b) This implies that C can be seen as the boundary of the surface S which is...

Please help me with these questions, show working. thankyou A space curve is defined by C: T(s) 2si+(5s2+4)j+(s+7)k. Determine parametric equations for the tangent line to the space curve C at the point P: (2, 9, 8) Your answer should consist of three expressions for the Cartesian variables x, y and z in terms of the parameter t, using the correct syntax. For example: x 2+4*t, y 7-3*t, z 15+2*t Do not use decimal approximations all numbers should be entered...
