Questions & Answers

Q: How do you differentiate the product of two integral functions?

To differentiate the product of two integral functions, we use the product rule. We keep the first function as it is and differentiate the second function, then add the two results together.

Q: How do you differentiate an integral function with a variable as an upper limit?

To differentiate an integral function with a variable as an upper limit, we substitute the variable into the integral function and differentiate the result, taking into account the chain rule.

Q: What is the fundamental theorem of calculus?

The fundamental theorem of calculus states that if F(x) is an antiderivative of f(x), then the definite integral of f(x) from a to b can be evaluated by subtracting F(a) from F(b).

Q: Why don't we need to include the absolute value when taking the natural logarithm?

In this case, we don't need the absolute value because the function inside the natural logarithm is always positive. If there is a possibility of a negative argument, we would need to consider the absolute value.
