To differentiate ( f(g(x)) ) using the chain rule, follow these steps:
 Find the derivative of ( g(x) ) with respect to ( x ), denoted as ( g'(x) ).
 Substitute ( g(x) ) into ( f(x) ) to get ( f(g(x)) ).
 Differentiate ( f(g(x)) ) with respect to ( x ).
 Apply the chain rule by multiplying the derivative of the outer function ( f ) with the derivative of the inner function ( g(x) ), i.e., ( f'(g(x)) \cdot g'(x) ).
So, to find ( \frac{d}{dx}[f(g(x))] ):

Find ( g'(x) ) by differentiating ( g(x) ). ( g'(x) = 5e^{5x} )

Substitute ( g(x) ) into ( f(x) ) to get ( f(g(x)) ). ( f(g(x)) = \tan^8(g(x)) )

Differentiate ( f(g(x)) ) with respect to ( x ). ( \frac{d}{dx}[f(g(x))] = 8\tan^7(g(x)) \cdot \sec^2(g(x)) \cdot g'(x) )

Finally, substitute ( g'(x) ) into the expression derived in step 3 to get the final result. ( \frac{d}{dx}[f(g(x))] = 8\tan^7(g(x)) \cdot \sec^2(g(x)) \cdot 5e^{5x} )

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
