Question statement

Differentiate the following.

Do not write out $dy/dx$ ; only input the differentiated right hand side of each equation. Make sure to put ( ) on both the top and bottom of a fraction. "/" is the line for fraction.

Give any introductory information the student needs.

			Name	Type	Generated Value

			c	list	[ 2, 7, 5, 5, 2, 7, 6, 3 ]
			p	integer	4

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$y=\var{c[1]}\ln(\var{c[2]}x)$

$\frac{dy}{dx}=$ Unnamed gap

Advice

The differentiate of $\ln(x)$ is $\frac{1}{x}$ .

This proof can be found here.

For natural logarithms in the form $u\ln(a(x))$ where $a(x)$ is a function of $x$ , the derivative is $u\frac{a'(x)}{a(x)}$ .

Give a worked solution to the whole question.
