    1. Find the gradient of the function f : x^2y/ z at the point M(-2;3;4).
    What is the directional derivative of this function in the direction of vector
    I =(12;-4;3)?

    2. Find the gradient of the scalar function f = cos(|r|^n) , Where
    r : (X, y, Z).
    Write the result as a function of r

    3. Find the normal line to the level curve of the surface given by
    X^2 + 3y^2/2 = 7 at point M(2;-1).

    4. Calculate the divergence of the vector Q : (X^2, y^3, XZ^3) at the
    field:point (A1,1,3).

    5. Calculate the curl of the vector field: a = (Z^2, X^2, y^2) at the point

    6. Calculate curl(r/r^n)

    Use of the "nabla" symbol (V):
