# Question

Use the theorems of this section to find f1 for the following:

a. f(x, y, z) = xy

b. f(x, y) = sin (xsin (y)).

c. f(x, y, z) = sin (xsin (ysin (z))

d. f(x, y, z) = xy2

e. f(x, y, z) =xy+z

f. f(x, y, z) =(x + y)z

g. f(x, y) = sin (xy)

h. f(x, y) = sin (xy) cos(3)

i. f(x, y) =(sin(xy), sin (xsin (y)),xy)

a. f(x, y, z) = xy

b. f(x, y) = sin (xsin (y)).

c. f(x, y, z) = sin (xsin (ysin (z))

d. f(x, y, z) = xy2

e. f(x, y, z) =xy+z

f. f(x, y, z) =(x + y)z

g. f(x, y) = sin (xy)

h. f(x, y) = sin (xy) cos(3)

i. f(x, y) =(sin(xy), sin (xsin (y)),xy)
