Verify the first special case of the chain rule for the composition f∘c in each of the cases:
(a) f(x, y)=xy, c(t)=(et, cost)
(b) f(x, y)=exy, c(t)=(3t2,t3)
(c) f(x, y)=(x2+y2)log√x2+y2,c(t)=(et, e−t)
(d) f(x, y)=xexp(x2+y2),c(t)=(t,−t)

7/2

(decimal: 3.5)

welcome ; )

step-by-step explanation:

the answer is 1030 it's very simple math.

answer: b

step-by-step explanation:

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
