Understanding Derivatives with Product and Chain Rules

The video tutorial explains how to determine the derivative of a function using the product and chain rules. It begins by identifying the need for these rules due to the function's structure. The tutorial then applies the product rule to differentiate the function, followed by the chain rule for the composite part. After finding the derivative, the video demonstrates how to simplify the expression using algebraic techniques, including factoring. The tutorial concludes with a factored form of the derivative and a brief overview of the process.

What is the main challenge in finding the derivative of the given function?

• The function is already in its simplest form.

• The function is a trigonometric function.

• The function involves a product and a power.

• The function is a simple polynomial.

Which rule is necessary to apply when dealing with the product of two functions?

• Power Rule

• Quotient Rule

• Product Rule

• Sum Rule

What is the first step in applying the product rule to the given functions?

• Apply the chain rule first.

• Differentiate the entire function directly.

• Simplify the function before differentiating.

• Identify and differentiate each function separately.

What is the purpose of introducing the variable 'U' in the chain rule application?

• To simplify the outer function.

• To represent the entire function.

• To isolate the inner function for differentiation.

• To eliminate the need for the product rule.

How is the derivative of the inner function 'U' calculated?

• By using the quotient rule.

• By differentiating with respect to 'U' and multiplying by 'U' prime.

• By integrating the function.

• By applying the product rule.

What is the greatest common factor identified in the simplification process?

• 2 and three factors of 7X squared - 2

• 14X and one factor of 7X squared - 2

• 4 and two factors of 7X squared - 2

• 7X squared - 2

What is the final form of the derivative after combining like terms?

• 14X squared - 4

• 2 times the quantity 7X squared - 2 to the 3rd times 63X squared - 2
