Explanation:
Assuming that you know the derivative rule:
Then
If you want to easily understand chain rule, just remember my tips: take the normal derivative of the outside (ignoring whatever is inside the parenthesis) and then multiply it by the derivative of the inside (stuff inside the parenthesis)
Explanation:
The first thing to realize is that we're dealing with a composite function
When we differentiate a composite function, we use the Chain Rule
From the definition of tangent and an application of the Quotient Rule, we know that
We also know that
