Example Question #55 : Parametric, Polar, And Vector

Find   when  and .

Possible Answers:

Correct answer:

Explanation:

If  and , then we can use the chain rule to define  as 

.  

We use the power rules

  and where  is a constant, the constant rule

 where   is a constant, and the additive property of derviatives 

.

In this case

 

 and

 ,

therefore
