To show that F(x)F(y)=F(x+y), we will perform matrix multiplication and use trigonometric identities. Let's proceed step by step. Proof. We use the fact that |cos/ x| = | − sinx| ≤ 1 for all x ∈ R. Let x, y ∈ R. If x = y, then |cosx−cosy| = 0 ≤ |x−y|. Now suppose x 6= y. Sep 19, 2012 ... Then integrate term by term to obtain ∫π/40log(cos(x))dx=−π4log2+iπ232+i2∞∑k=1(−1)k+1k2[e−ikπ/2−1].
