Problem 7.5.21

find the third-order Fourier approximation to f on 3p, p4.7

Step-by-Step Solution:
Step 1 of 3

Rational Expressions­ 2/15/16 Relatively Prime­ numbers that aren’t prime but their least common denominator is those two numbers multiplied together. Ex. 8 and 9. Prime Polynomial­ does not factor into polynomials of a smaller degree. To Add Fractions: 1. Find the least common denominator. 2. Multiply the denominator of each fraction to make the least common denominator. 3. Add the numerators. Fractions “Rule of Thumb”­ with variables in the denominator, the least common denominator is always the largest power. Rational Expressions “Rule of Thumb”­ If you can, factor out a non­trivial (not 1) greatest common factor first. Rational Expression­ P/Q, where P and Q are polynomials and Q ≠ 0; the numerator can be zero as long as the denominator isn’t. Domain­ set of all allowable values that we can plug in to get a denominator ≠ 0. Addition / Subtraction­ a/c + b/c = a+b/c Multiplication / Division­ a/c x b/d = a x b/ c x d m n m­n Quotient Rule­ m > n, a / a = a Rational Exponent­ a = ( √a) , n ≠ 0 Index­ the superscript on the root symbol, indicates degree to which the root is taken. Ex. square root has an index of 2, cube root index of 3, etc. Radicand­ the value within the root symbol. **When faced with a negative exponent, make it positive** When Radicals are Simplified: 1. Radicand will have no factor raised to a power greater than or equal to the index. 2. The radicand has no fractions. 3. Exponents and indices are relativel
