1. Find the domain of these functions.
1.26 z = 7x3y / (x - 4y)

2. Find the partial derivatives and partial differentials of the following functions.
2.26 z = arccos (x - y2)
 
3. Calculate the value of partial f´x (M0), f´y (M0), f´z (M0), for the function f (x, y, z) at the point M0 (x0, y0, z0) with an accuracy of to two decimal places
3.26 f (x, y, z) = √zln (√x + √y), M0 (4 1, 4)

4. Find the total differentials of these functions.
4.26 z = ln (y2 - x2 + 3)

5. Calculate the value of the derivative of a composite function u = u (x, y), where x = x (t), y = y (t), at t = t0 up to two decimal places.
5.26 u = arcsin (2x / y), x = sint, y = cost, t0 = π

6. Calculate the values of the partial derivatives of the function z (x, y) given implicitly at the point M0 (x0, y0, z0) accurate to two decimal places.
