Reading about OFDM and it states that orthogonal frequencies can exist and not interfere with one another because of the fact that a sinusoidal wave multiplied by another sinusoid of a different harmonic is 0.
How can you demonstrate mathematically that a sinusoidal wave multiplied by another sinusoid of a different harmonic is 0? Unfortunately the book does show a mathematical expression.
