Questions & Answers

Q: Why is adding fractions challenging?

Adding fractions can be difficult because the denominators may be different, requiring the use of a common denominator. Additionally, when dealing with fractions in decimal form, the numbers can be complicated, making addition more challenging.

Q: How can converting fractions to decimals make addition easier?

Converting fractions to decimals eliminates the need for finding a common denominator. It allows for adding the numbers term by term, similar to adding numbers in the place value system.

Q: What are the advantages of converting functions to polynomials?

Converting functions like e^x and 1/(1-x) to polynomials makes addition easier because polynomials can be added term by term. This simplifies the process and allows for finding the sum of the functions.

Q: What is the Taylor series?

The Taylor series is a power series that represents a function as an infinite polynomial. It can be used to approximate a complicated function by finding its coefficients and center. The Taylor series is a useful tool in calculus.
