WebThe product rule is if the two "parts" of the function are being multiplied together, and the chain rule is if they are being composed. For instance, to find the derivative of f (x) = x² sin (x), you use the product rule, and to find the derivative of g (x) = sin (x²) you use the chain rule. See the difference? 2 comments ( 58 votes) Show more... WebThe chain rule as multiplying slopes. The chain rule for the derivative of the composition h ( x) = f ( g ( x)) of two functions f and g can be thought of as the product of the tangent line slopes. The trick is to evaluate the slopes at the correct points of the functions f and g.

"WebWe can always use the power rule instead of the quotient rule. However, this isn't possible without another rule called the chain rule, so it's best to stick with the quotient rule until you learn the chain rule. On another note, I believe you may have made a mistake in your use of the quotient rule for your g (x) function. " - How does the chain rule work

WebJul 2, 2015 · The chain rule says do the derivative like normal (just treat the x 2 like an x ), then multiply by the derivative of the inside function. So we get d d x ( tan ( x 2)) = sec 2 ( x 2) ⋅ 2 x = 2 x sec 2 ( x 2) Another way people write this a lot of times is d y d x = d y d u ⋅ d u d x where u is the "embedded" function.
