ABSOLUTE VALUE INEQUALITIES. Just like absolute value equations, inequalities will have two solutions: |3x - 2| ≤ 7 3x – 2 ≤ 7 +2 +2 3x ≤ 9 x ≤ 3 -5/3.

Chapt.12: Orthogonal Functions and Fourier series · • Example: f(x) = sin(3x), g(x) = cos(3x). We have Zπ −π sin(3x) cos(3x)dx = 0 since sin(3x) cos(3x) is odd and the interval
