Advice

If you don't know how to differentiate trigonometric functions, please see 'Differentiation 4 - Trigonometric Functions'.

These questions use the chain rule.

The earlier questions are easy to do by inspection, e.g using Part a:

$y=sin(\var{c[0]}x)$ .

We differentiate the term(s) inside the function, here the term is $\var{c[0]}x$ .

Then we derive $sin$ of any function, giving us $cos$ .

Putting our results together, we get

$\var{c[0]}cos(\var{c[0]}x)$ .

We will now go through an entire worked example of the formal method of the chain rule using Part e.

The expression we will be differentiating here is

$y=tan^\var{p[0]}(x)$ .

As a reminder, the chain rule is defined as

$\frac{dy}{dx}=\frac{dy}{du}\times\frac{du}{dx}$ .

Now we let $u=tanx$ , so then $y=u^\var{p[0]}$

This becomes an easy differentiation using $\frac{dy}{du}\times\frac{du}{dx}$ :

Differentiate $y$ with respect to $u$ , giving $\simplify{{p[0]}u^{{p[0]}-1}}$ .

Then differentiate $u$ with respect to $x$ , giving $sec^2x$ .

Multiply these results together, and substitue $tan$ back in for $u$ .

Your final result is therefore

$\simplify{{p[0]}(tan^{{p[0]}-1}(x))*sec^2(x)}$ .

Give a worked solution to the whole question.
