Module 5 Quiz

Solve the problems below and write up a solution to each problem using complete English sentences and well-organized calculations as appropriate. Your solution will be graded based on mathematical accuracy and clarity of presentation.

Late submissions will not be accepted. You must submit your responses as a single .pdf file that includes all pages of your solution. You may resubmit until the deadline but only the most recent submission will be graded. Quiz submissions will not be accepted via e-mail. After submitting you must download your file to ensure that it submitted properly. See technical instructions on Module Quiz submissions.

Problem 1:

Find all the values of xxxx where the function f(x)=5exsinxf(x)=5exsinxff ( x ) = 5 e x sin  x has a horizontal tangent line.

Problem 2:

Assume that ffff and gggg are differentiable functions. Find the derivative of y=f(x)[g(x)]−1y=f(x)[g(x)]−1yy = f ( x ) [ g ( x ) ] − 1 using the Product Rule and Chain Rule. Explain how this calculation relates to the Quotient Rule.

Problem 3:

Find the derivative of the function f(x)=ln(x3+1x2+1)f(x)=ln(x3+1x2+1)ff ( x ) = ln  ( x 3 + 1 x 2 + 1 ).
