Looking for help on the first half, not the Marine Biology question.

• For the function f (x) = cot (x):
• Rewrite f (x) as a composite function f (x) =g(h (x)).
• How did you decide what g (x) and h (x) are?
• Find f (x) using the Chain Rule and your decomposition g (h (x)).
Find the derivatives of each of the following functions, telling me how you choose the rules you use, and showing your
3.
process. It might help to use the strategies shown in the videos to organize your work for multiple "chain links", especially if
there are also other rules involved.
f (x) = 3tan(5a)
o y = sin* 2x cos 3x + sin 2x
f (t) = et lu(3t)
In the videos this week, we stated without proof that y
is the derivative of y = In a, after conjecturing that this
might be the case based on the asymptotic behavior of the tangent lines as z- 0 and r - 0o. Use the Inverse Function
Theorem, and the fact that y= e andy =
In are inverses of each other, to show that this derivative is correct.
In the videos this week, we used the Inverse Function Theorem to find the derivative of the arcsine (inverse sine) function.
This included a process where we drew a triangle and rewrote the derivative using identities. Use a similar process to
verify the derivatives of the arccosine and arctangent functions.
Application - Marine Biology
You are studying the impacts of rising sea levels on an estuary, and are modeling how the salinity of a particular area changes
with the tidal cycle. The salinity is also impacted seasonally by snowmelt increasing river flows, so measurements are often
taken in early autumn for this particular area. The mixed-tide cycle on this part of the coast has a period of approximately 25
