4. Recall that 4 (In z) = 1, () =e², and that (a=) =a* In a, where a >0 is a constant
(as deduced in class). Apply the Power Rule, combined to the Constant Multiple Rule, the
Sum Rule, the Difference Rule, the Product Rule, the Quotient Rule, and/or the Chain
Rule to compute the derivative of each one of the following functions:
a)
f(2) = VE
b)
S(2) = V/#+4z –5
c)
f(2) = In (z² + 7)
d)
f(z) = In (In z)
e)
f(z) = /3sin(5z)
f)
sin z
f(2) =
cos z
Bring your ansuer to the simplest possible form.
g)
S(2) = e==
h)
f(<) = 2* + !
i)
f(z) = z(4*) +7
j)
S(2) = V2
5. Now, explain the difference between the following two examples from the point of view of
differentiation:
d
(29)s00 P
and
dz cos"(z)
Compute explicitly each one of them.
6. Based on our class discussions, recall that some functions are defined implicitly by a relation
between z and y such as z+y = 25. In such cases, differentiating with respect to z both sides
helps us compute . We should be careful, however, with the Chain Rule that needs to be applied
in the way. That is, if y is assumed to be a function of z, then
(1²Y = 2y(3/')
(e®Y = (e®)v/
and so on.
