Question:medium

If the surface $mx^{2} - 2nyz = (m + 4)x$ is orthogonal to the surface $4x^{2}y + z^{3} = 4$ at the point (1, -1, 2), then the values m and n will be}

Show Hint

Orthogonal surfaces mean their normals (gradients) are perpendicular.

Let $ R $ be the planar region bounded by the lines $ x = 0 $, $ y = 0 $ and the curve $ x^2 + y^2 = 4 $ in the first quadrant. Let $ C $ be the boundary of $ R $, oriented counter clockwise. Then, the value of:
\[ \oint_C x(1 - y) \, dx + (x^2 - y^2) \, dy \] is equal to:
