Integral from 0 to pi/6 of (sin x + cos x) less than or equal to pi(square root 3 + 1)/12

Answer 1

The integral is (-cos x + sin x)[0,π/6]
= (-√3/2 + 1/2) - (-1 + 0) = 3/2 - √3/2 = 0.63397

π(√3 + 1)/12 = 0.71525

the statement is true

It's kind of a weird question, since the integral value has nothing to do with π.
